Question

what is rasistance?and its unit and formula??​

Answer 1

Restriction for the movement of electrons in a conductor is known as resistance.

It's units are ohms

V = IR

R = V/I

where V = potential difference

I = current

Answer 2

Resistance :

Resistance is the ratio between the voltage applied to the current flowing through it.

Unit :

The unit of electrical resistance is ohm (Ω).

Formula :

Resistance = Potential difference/current

R = V/I
