10 kΩ and 1 kΩ resistors
Tuning potentiometer
The resistors in the kit are of the carbon film type and can
be mounted in any direction. The smallest one has a resis
-
tance of 100 ohm (100 Ω), the biggest one has 220 kiloohm
(220 kΩ). The resistance values are shown by three coloured
rings. The fourth, gold ring represents a tolerance of 5%. The
kit contains four resistors in total.
100 Ω: brown, black, brown
1 kΩ: brown, black, red
10 kΩ: brown, black, orange
220 kΩ: red, red, yellow
Basically, a potentiometer
is a resistor; however, it contains a
third contact, which is shifted by turning the axis. The poten
-
tiometer will be mounted in the radio housing with a washer
and a nut, and a rotary knob will be screwed to the axis. This
three-pin potentiometer is intended for tuning the radio.
