Revise: Electrical Energy DissipationAs charge moves through it, the current does work against the electrical resistance. Work done is another way of describing energy transferred, so the electrical energy transferred to the resistor does not disappear: it increases the thermal energy of the resistor and raises its temperature.
- Revise: Reducing Unwanted Energy Transfer
A measure of how strongly a component or conductor opposes an electric current, measured in ohms (Ω).
