Resistance — The opposition to the passage of an electric current. Electrical resistance can be compared to the friction experienced by water when flowing through a pipe. Measured in ohms.

Resistor — A device usually made of wire or carbon which presents a resistance to current flow.

Rotor — The rotating part of an electrical machine such as a generator, motor, or alternator.
Self Induction — Voltage which occurs in a coil when there is a change of current.

Semiconductor — A solid substance that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects. Devices made of semiconductors, notably silicon, are essential components of most electronic circuits.

Series-Parallel Circuit — A circuit in which some of the circuit components are connected in series and others are connected in parallel.
