a) Fixed resistors- offer fixed values of resistance. They have colour bands around them.
b) Variable resistors- offer varying resistance e.g rheostat and potentiometer.
c) Non-linear resistors- the current flowing through these resistors does not change linearly with the voltage applied. Examples include a thermistor and light-dependent resistor (LDR).
