What units are used to measure the electrical resistance of a circuit?

Explanation:
Resistance is measured in the unit called the ohm. This unit comes from Ohm’s law, which relates voltage, current, and resistance with V = IR. From that relationship, resistance is the ratio of voltage to current, so one ohm is defined as one volt per ampere. Volts measure electrical potential difference, amperes measure current, and joules measure energy, so they describe other aspects of circuits, not resistance.
