A Heating Element Having a Resistance (At Its Operating Temperature) $148 \Omega$

Short Answer

A heating element having a resistance (at its operating temperature) of $148 \Omega$ is connected to a battery having an emf of $523 \mathrm {~V}$ and unknown internal resistance.It is found that heat energy is being generated in the resistance of the heating element at a rate of $66.0 \mathrm {~W}$ . What is the rate at which heat energy is being generated in the internal resistance of the battery?
