3.1.8 Resistors
A resistor is a passive component in electric and electronic circuits. Its main
task is the reduction of the flowing current to “reasonable” values. The most
famous resistors are the cylindrical ceramic type with axial connection
wires. The resistance values are imprinted in the form of coded coloured
rings. Enclosed are carbon-film resistors with the different values, shown in
the following table.

the resistor. It does not matter on which side it is connected.
