Answer:
- Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit. To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc²) is to physicists. E = I x R.

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

E = I x R
When spelled out, it means voltage = current x resistance, or volts = amps x ohms, or V = A x Ω.
