Question

4.
State Ohm's law. Give the SI unit of current.​

Answer 1

Answer:

1. the principle that the electric current passing through a conductor is directly proportional to the potential difference across it, provided that the temperature remains constant. The constant of proportionality is the resistance of the conductor.

2. ampere

The ampere, symbol A, is the SI unit of electric current.

Answer 2

Ohm’s law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm’s law is V=IR.

The SI unit of resistance is ohms and is denoted by Ω
