Answer:
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.

Answer:
Ohm’s law states that Current (I) through a conductor is directly proportional to the potential difference(V) applied across the ends of the conductor, provided physical conditions of the conductor like temperature, pressure, density etc., remain constant. (V α I)
SI Unit: Ohm (Ω)
