R

In electrical engineering, symbolically represents resistance, the property of a material that opposes the flow of electric current, measured in ohms (Ω).

Z

Often represents impedance in electrical circuits, a measure of opposition to AC including both resistance and reactance.

RC Parallel Circuit
