Q1 · Difficulty 1/3
What is Ohm's Law?
- F = ma
- V = IR (voltage = current × resistance)
- E = mc²
- P = IV
Show answer & explanation
✓ Answer: B — V = IR (voltage = current × resistance)
Ohm's Law states that voltage across a conductor equals the current through it times its resistance: V = IR. Units: volts, amps, ohms.
