A measure of how strongly a component opposes the flow of electric charge, measured in ohms (Ω).
Revise: Current, resistance and potential differenceComponents oppose that flow; this opposition is called resistance.
- Revise: Ohmic and Non-Ohmic Circuit Elements
The opposition of a component to the flow of electric current, measured in ohms (Ω). At an operating point, it is given by .
