Question

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

Answer 1

Answer:

The electrical resistance of a circuit is the ratio between the voltage applied to the current flowing through it. Rearranging the above relation, R = \frac VI. The unit of electrical resistance is ohms. ohm = \frac {1~ volt}{ 1 ~ampere}

Explanation:

I hope it will be help you ❤️❤️❤️

Answer 2

Resistance is a property of conductor due to which it resists the flow of electric current through it. A component that is used to resist the flow of electric current in a circuit is called a resistor.

Formula - R = V/I, where

V is the potential difference measured across the conductor (in volts)

I is the current through the conductor (in amperes)

R is the constant of proportionality called resistance (in ohms)

Unit - ohms
