What is Ohm's Law?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Ohm's Law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, with resistance (R) being the constant of proportionality. The formula is V = IR, where V is voltage in volts, I is current in amperes, and R is resistance in ohms. This fundamental law helps you understand the relationship between these three electrical quantities in any circuit.
