b) Resistors
First you bend the connection wires of the resistors according to the modular dimension and inserted in the provided borings (see equipment
plan). To prevent the components from falling out when turning the circuit board, bend the connection wires of the resistors at a 40° angle and
then solder these together carefully with the conductors on the back of the circuit board. Now cut off the excess wires.
Carbon layer resistors usually have four colour rings, metal layer resistors have five of them. To read off the colour code, hold the resistors in
such a way that the tolerance ring is located on the right side of the resistor. Read the colour rings from left to right!
