Question

(i) Define resistance and 1 ohm.
​

Answer 1

Answer: 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.

Explanation:

Answer 2

Resistance:

The degree to which a material opposes the passage of current through itself, is called as Resistance.

1 Ohm:

If a potential difference of $\sf{1}$ volt is applied across an element, and a current of $\sf{1}$ ampere passes through it, the resistance of the element is called $\sf{1}$ Ohm.
