An immersion heater of resistance R converts electrical energy into thermal energy that is transferred to the liquid in which the heater is immersed. If the current in the heater is I, the thermal energy transferred to the liquid in time t is ?
The answer is I^2RT, but I don't understand why. Please help. Thank You.

power= I^2 R watts.
Energy= power*time
