Question

8.

The resistance of a copper wire is 50 22 at a temperature of 35°C. If the wire is heated to
a temperature of 80°C, find its resistance at that temperature. Assume the temperature
co-efficient of resistance of copper at 0°C to be 0.00427 per °C. Also find the
temperature co-efficient at 35°C.
(58.35 22, 0.00372 per °C)
