A coil has a resistance of 18 when it mean temp is from 20o C to 50o C. Find its mean temp rise when its resistance is 21 and the surrounding temp is 15o C.A potential difference of 250 V is applied to a copper field coil at a temp of 15o C and the current is 5A. What will be the mean temp of the coil when the current has fallen to 3.91 A, the applied voltage being the same as before.
