A: When temperature of a metallic wire is increased, its resistance increase .
R : As the temperature is increaed , average relaxtion time increase.

When the temperature of a metallic conductor is increased, its resistance

When temperature of a metal increases ,

When temperature of metal increases, does the resistance increases or decreases?

Assertion: When we increase the temperature of a metal wire then its electrical resistance increases. Reason: When we increase the temperature of a conductor then its relaxation time also increases.

Resistance increases with increases in temperature for

Resistance increases with increases in temperature for
