What do V and I represent in the formula V = IR?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
In Ohm's Law (V = IR), V represents voltage (also called potential difference or electromotive force), measured in volts. I represents current, which is the flow of electric charge through a conductor, measured in amperes (amps). These variables work together with resistance (R) to describe how electricity behaves in a circuit.
