• Complete all wiring connections as indicated in the sequence. After switching ON for a
time period, motor will start to rotate. This delay is due to the charging of the capacitor.
During the charging, the base electrode of the triode is in a low voltage so that the triode is shut. When the capacitor is
charged fully, the triode is in its conducting condition, thus the motor will rotate. The time-delay period is the duration of the
charging.
NOTE: Every time when you perform this experiment once, remember to “discharge” the capacitor before doing it again.
Otherwise it won’t work. To “discharge”, connect any wire to 72-73 for a second. This way the electricity stored in the
capacitor will be “discharged” and then the experiment can work again.
WARNING:
Take away the color filter in this experiment. Do not connect the color filter with the motor. Otherwise
components will get overheated.
• Complete all wiring connections as indicated in the
sequence. Switch on the main switch. Turn the variable
resistor from the minimum to the maximum settings.
Adjust the variable resistor to a point which just will not
trigger the color filter to rotate. This time, clap near the
microphone, or blow to the microphone, or simply speak
loudly will cause the color filter to rotate.
• Complete all wiring connections as indicated in the
sequence. Switch on the main switch and touch the
touching-plate with your finger. The circuit will be
connected and motor will begin to rotate. If touching the
touching-plate does not show anything, dampen your
finger with water before touching will make it works.
And remember to wipe the water off the touch plate after
you remove your finger from it.
WARNING:
Take away the color filter in this experiment.
Do not connect the color filter with the motor. Otherwise
components will get overheated.
• Complete all wiring connections
as indicated in the sequence.
Switch on the main switch and
adjust the variable resistor slowly to a suitable position.
LED and electric motor will work alternately. The
frequency of the alternation can be changed according
to the adjusting of the variable resistor. Adjusting the
variable resistor to its maximum, the electric motor will
rotate and green LED will extinguish. Adjusting the
variable resistor to its minimum, the electric motor will
stop and green LED will light up.
WARNING:
Take away the color filter in this experiment.
Do not connect the color filter with the motor. Otherwise
components will get overheated.
• Complete
all
wiring
connections as indicated in
the sequence. Switch on the
main switch. Adjust the variable resistor slowly. This
will change the control voltage of the triode, thus the
speed of the motor will change. Utilizing this
principle can get a speed-adjustable electric motor.
WARNING: Take away the color filter in this
experiment. Do not connect the color filter with
the motor. Otherwise components will get
overheated.
• Complete all wiring connections
as indicated in the sequence.
Switch on the main switch. Turn the variable resistor to
minimum. Red LED will light up and green LED will
extinguish. Turn the variable resistor to maximum.
Green LED will light up and red LED will extinguish. This
principle can be used for indicating the change of
direction of automobile, as different direction will cause
different LED to light up and extinguish.
• Complete all wiring connections
as indicated in the sequence.
Switch on the main switch. Drop a
drop of water on the touch-plate, then red LED will light
up and green LED will extinguish. Wipe the water off
the touch-plate. Then green LED will light up and red LED
will extinguish. This principle can be used for rain
indicating or water-level warning. When it rains or
water-level goes beyond warning level, red LED will
light up, green LED will extinguish. Otherwise red LED
will extinguish and green LED will light up.
• Complete all wiring connections
as indicated in the sequence.
Switch on the main switch.
Green LED will light up while red LED will not. Shade the
LDR a little bit, green LED will become dimmer. Shade
the LDR a bit more, then green LED will extinguish and
red LED will start to light dimly. When the LDR is covered
completely, green LED will extinguish and red LED will
light up completely. This principle can be used as light
indicator, to reflect the amount of light shining on the
indicator.
• Complete all wiring connections
as indicated in the sequence.
Switch on the main switch.
Green LED will light up and red
LED extinguish. Press the push switch. Red LED will light
up and green LED extinguish. This principle can be use
for indicating the break/connect of circuit: When the
door, car-door or window is closed, this is just like the
push switch is being pressed, and thus red LED lights up
while green LED does not. When the door, car-door or
window is opened, this is just like the push switch is
released, and thus green LED lights up while red LED
does not.
• Complete all wiring connections
as indicated in the sequence.
Switch on the main switch, then the motor will rotate.
Now cover the LRD completely. The motor will stop
rotating for a while. However, after keeping on covering
the LDR for a time period, the motor will suddenly start to
rotate again! If you uncover the LDR, then the motor will
rotate even faster for a while! After some time, the
rotating speed will gradually back to normal. Cover the
LDR again will stop the rotation again and the process
mentioned above can be repeated.
WARNING:
Take away the color filter in this
experiment. Do not connect the color filter with the
motor. Otherwise components will get overheated.
• Complete
all
wiring
connections as indicated in the
sequence. Switch on the main switch, then after a while the
motor will rotate. Access the reed switch with the magnetic
pole. The rotation speed will be changed for a while, and
gradually back to the original rotation speed. Remove the
magnetic pole, and then the rotation will stop for a while.
After waiting for some time, the rotation will resume again
like it did at the beginning of the experiment!
WARNING:
Take away the color filter in this
experiment. Do not connect the color filter with the
motor. Otherwise components will get overheated.
• Complete
all
wiring
connections as indicated in
the sequence. Switch on the main switch, then after a
while the motor will rotate. Press the push switch, and
the rotation speed will increase for a while. Do not
release the push switch, and the speed will gradually
back to the original rotation speed. And then release the
push switch. The rotation will stop for a while. After
waiting for some time, the rotation will resume again like
it did at the beginning of the experiment!
WARNING:
Take away the color filter in this experiment.
Do not connect the color filter with the motor. Otherwise
components will get overheated.
• Complete
all
wiring
connections as indicated in
the sequence. Switch on the main switch. LED will light
up. Then cover the LDR completely. LED will extinguish.
Do not uncover the LDR and wait. After a while, LED will
light up again! And then if you uncover the LDR, the
statue will be just like the beginning of the experiment.
You can repeat the experiment without switching off the
main switch.
• Complete all wiring connections as indicated in the
sequence. Switch on the main switch. LED will light up.
Use the magnetic pole to access the reed switch, and then
remove the magnetic pole. LED will extinguish. Then wait
for a time period, LED will light up again! You can repeat
the experiment without switching off the main switch.
NOTE: Every time when you perform this experiment
once, remember to “discharge” the capacitor before
doing it again. Otherwise it won’t work. To “discharge”,
connect any wire to 72-73 for a second. This way the
electricity stored in the capacitor will be “discharged”
and then the experiment can work again.
• Complete all wiring connections as indicated in the
sequence. Switch on the main switch. LED will light up.
Press the push switch, and then release it. LED will
extinguish. Then wait for a time period, LED will light up
again! You can repeat the experiment without switching
off the main switch.
• Connect all wiring connections as indicated in the
sequence. Switch on the main switch. Red LED will light
up while green LED will not. Then press the push switch.
The green LED will also light up.
When you release the push switch, green LED will
extinguish while red LED will keep on lighting. You will
have to switch off the main switch to turn red LED off.
• Complete all wiring connections as indicated in the
sequence. Switch on the main switch. Adjust the
variable resistor from minimum to maximum, and the
brightness of the LED will change from dim to bright.
• Complete
all
wiring
connections as indicated in
the sequence. Switch on the
main switch and press the push switch. Electricity will
flow through the triode so that LED will light up. At the
same time the capacitor is being charged. Release the
push switch. The triode can still keep conductive for
some time, as the capacitor will release the stored
electricity. Therefore the LED will not extinguish immedi-
ately after you release the push switch.
• Complete
all
wiring
connections as indicated in
the sequence. Switch on
the main switch. Use the magnetic pole to access the
reed switch. The circuit is connected and LED will light
up. At the same time the capacitor is being charged.
Remove the magnetic pole. The triode can still be
conductive for some time, as the capacitor will release
the stored electricity. Therefore the LED will not
extinguish immediately after you remove the magnetic
pole.
• Complete
all
wiring
connections as indicated in
the sequence. Switch on the
main switch. Touch the touch-plate with finger. You may
have to dampen your finger with water before
touching. The circuit is then connected and electricity
will flow through the triode so that LED will light up. At
the same time the capacitor is being charged. Then
remove your finger. Note that you may have to wipe
the water off the touch-plate. You will see the triode can
still keep conductive for some time as the capacitor will
release the stored electricity. Therefore the LED will not
extinguish immediately after you remove your finger
from the touch-plate.
• Complete
all
wiring
connections as indicated in
the sequence. Switch on
the main switch. Cover the LDR completely, the LED will
light up. Uncover the LDR and shine it with bright light.
Then the LED will extinguish. This is because of the light
falling on the LDR changes its resistance.
• Complete
all
wiring
connections as indicated in
the sequence. Switch on the
main switch. LED will light up. Cover the LDR
completely, and wait for some time. The LED will
become dimmer and dimmer gradually. Finally it will
extinguish. If you take away the cover thing, the LED
will light up immediately. You can repeat the
experiment by covering the LDR again for some time.
• Complete
all
wiring
connections as indicated in
the sequence. Switch on the main switch. LED will light
up. Cover the LDR completely, then LED will extinguish.
Keep on covering the LDR for a while. After some time,
the LED will light up again! If you want to repeat the
experiment, just cover the LDR again.
