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
None of the above choices are valid.
D
None of the above
Explanation: 

Detailed explanation-1: -The basic function of an electromotive force in a circuit is to do which of the following? O Convert electrical energy into some other form.

Detailed explanation-2: -The emf source acts as a charge pump, moving negative charges from the positive terminal to the negative terminal to maintain the potential difference. This increases the potential energy of the charges and, therefore, the electric potential of the charges.

Detailed explanation-3: -Batteries are a source of EMF, providing potential energy for electricity from their chemical energy. Electromotive force (EMF) is a voltage developed by any source of electrical energy such as a battery or photovoltaic cell.

Detailed explanation-4: -Like other measures of energy per charge, emf uses the SI unit volt, which is equivalent to a joule (SI unit of energy) per coulomb (SI unit of charge).

Detailed explanation-5: -The electric potential produced by an electrochemical cell or by changing the magnetic field is referred to as electromotive force. EMF is an abbreviation for electromotive force. Energy is converted from one form to another using a generator or a battery.
