Question

in practical situations when an electric appliance is connected to a known voltage source equation 12.21 is used after calculating the current through it using the relationship but I = V/R explain the sentence

Answer 1

Answer:

Ohm's law is the relationship between potential difference across a conductor and the current flowing through it.

Ohm's law states that "The current flowing through a conductor is directly proportional to the potential difference between its ends provided its temperature remains constant.

That is, V∝I

orR= V/I

or V=IR

where R is a constant called resistance for a given metallic wire at a given temperature.
