Units of Quantities used in Ohm’s Law
Ohm’s law relates four basic electrical quantities. Let’s understand their units.
| Quantity | Symbol | Units | Abb |
|---|---|---|---|
| Voltage | V | volts | V |
| Current | I | ampere | A |
| Resistance | R | ohms | Ω |
| Power | P | watts | W |
All these quantities are linked together in Ohm’s law formulas.
V = IR & P = VI are the basic quantities which relate them.
The statement P = VI is actually Joule’s law.
