Question

Draw the nature of V - I graph for a nichrome wire. (V - Potential difference, 1 - Current)​

Answer 1

Answer:

The V-I graph of the nichrome wire shows a straight line. It means that the resistance of the wire remains constant when the current supply is changed. It follows the ohm's low and therefore, it is considered as ohmic conductor.

It follows the ohm's law →V=IR

R=
