Question

Define Ohm's law and what is meant by 1Ohm ?

Answer 1

→Define Ohm's Law :—

A law in electricity: the strength of a direct current is directly proportional to the potential difference and inversely proportional to the resistance of the circuit.

* 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.

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

Ohm’s Law Formula:—

→ Voltage= Current × Resistance

→ V = I × R

→ V = voltage,

→ I = current and

→ R = resistance

→ Define 1 ohm :—

1 Ohm is defined as the resistance of a conductor with a potential difference of 1 volt applied to the ends through which 1-ampere current flows. Ohms is the SI unit of electrical resistance.
