Answer 1

Hey Pawan,

You didnt give any options to choose from. But I'll explain relationship between V and I with an image.

◆ Ohm's law -

• According to Ohm's law, the potential difference between two points is directly proportional to the electricity passing through the wire.

V ∝ I

• Taking R = Resistance as a constant,

V = IR

• When potential difference (V) is plotted along with electric current passed (I), it is straight line with resistance as slope.

[Refer to the image for graph of voltage vs current.]

Hope this helped you...
