copper coil, when connected to a 30-volt supply, initially takes a current of 3 A and has a mean temperature of 20 C°. After some time, the coil's current falls to 2.85 A while the supply voltage remains the same. The mean temperature of the coil is then 33.4 Cº. Determine the temperature coefficient of resistance at 0 Cº.
