# 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.
