The basic function of an electromotive force in a circuit is to do which of the following?
A) Convert electrical energy into some other form.
B) Convert some other form of energy into electrical.
C) Both choices (a)and (b)are valid.
D) None of the above choices are valid.

Question

Quizplus · Accepted Answer

The basic function of an electromotive force is to convert some other form of energy (such as chemical, mechanical, or light) into electrical energy, which then powers the circuit. Option A is incorrect because EMF does not convert electrical energy into another form. Option C is incorrect because it only implies both choices, whereas only choice B directly addresses the function of EMF. Option D is incorrect because EMF is a valid concept in electrical engineering.
