What is electromotive force?

Electromotive force is defined as the electric potential produced by either electrochemical cell or by changing the magnetic field. EMF is the commonly used acronym for electromotive force. A generator or a battery is used for the conversion of energy from one form to another.

### What is electromotive force in biology?

Electromotive force is defined as the electric potential produced by either electrochemical cell or by changing the magnetic field.

### What is electromotive force class 12th?

Emf is defined as maximum work done per unit charge to take charge from one point to another. Emf provides an energy which does the work to move the charge from one point to another. As there is potential difference between the two electrodes the charges will flow.

What are common units of electrical force?

Common electrical units used in formulas and equations are: Volt – unit of electrical potential or motive force – potential is required to send one ampere of current through one ohm of resistance. Ohm – unit of resistance – one ohm is the resistance offered to the passage of one ampere when impelled by one volt.
