Answer:
Most basic components of electricity are voltage, current, and resistance. Ohm’s law shows a simple relation between these three quantities. Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

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. It helps to calculate the power, efficiency, current, voltage, and resistance of an element of an electrical circuit.
