An immersion heater of resistance R converts electrical energy into thermal energy that is transfered to the liquid in which the heater is immersed. If the current in the hearter is I, the thermal energy trasferred to the liquid in time t is?(adsbygoogle = window.adsbygoogle || []).push({});

1) IRt

2) I^2Rt

3) IR^2t

4) IRt^2

5) IR/t

The answer is #2 but I dont see how my book got that answer.
