pARALLEL CiRCUiT
pARALLEL CiRCUiT wiTH BULB AND
mOTOR wiTH LESS pOwER
Make a parallel circuit with one bulb, the motor with flying saucer and the
push button switch. Open and close the circuit and observe what happens.
The bulb lights up weakly. The filament is orange, but it does not give off
much light. The current flows in the circuit but it is not enough for the
electric components to work properly.
pARALLEL CiRCUiT wiTH TwO BULBS
AND mOTOR wiTH LESS pOwER
Make a circuit with two bulbs in series and the motor in parallel.
At first, do not use the discs and observe the brightness of the light
from the two bulbs. The filament is weak in colour, while the motor
runs.
If you put Newton’s optical disc on the motor, the colours will
disappear and the lights will go out as the motor needs more energy
and does not leave enough for the two bulbs.
