Question

Define ohm law give us a unit of resistance

Answer 1

Answer:

Ohm's Law Formula

Voltage= Current× Resistance. V= I×R. V= voltage, I= current and R= resistance. The SI unit of resistance is ohms and is denoted by Ω This law is one of the most basic laws of electricity.

Explanation:

Hope it helps you and mark me as brainliest plz!!!

Answer 2

Ohm's law is defined as the amount of current flowing through a metallic conductor is directly proportional to the potential difference applied to it.
Explanation:
1. V=IR where
V is potential difference
I is electric current
R is a constant and called resistance
2. Unit of resistance is ohm.
