Question

Mechanical energy is initially converted into thermal energy in the case of motional emf.

(a) True

(b) False

I have been asked this question by my school teacher while I was bunking the class.

Question is from Energy Consideration: A Quantitative Study in section Electromagnetic Induction of Physics – Class 12

Answer 1

Correct option is (b) False

For explanation: No, this statement is false. The work done is mechanical and the energy is dissipated as mechanical energy. Then it is initially converted into electric energy and then only finally converted into thermal energy.
