Question
An electric heater is connected, turn by turn, to a d.c. and a.c. sources of equal voltages. Will the rate of heat production be same in the two cases? Explain.
Solution
The rate of heat production in both the cases will be same. The rate of heat produced in a.c. and d.c. is resistance dependent and will behave in the same manner for both a.c. and d.c.
