EMF full form

The EMF full form is Electromotive Force. An electrochemical cell or a change in the magnetic field produces an electric potential defined as Electromotive Force. We generally use a generator or a battery to convert energy from one form to another. There is one positively charged terminal and a negatively charged terminal inc such electrical devices. Electromotive force is also defined as work done on a unit of electric charge. It is commonly used in electromagnetic flowmeters which is an application of Faraday’s Law.

What are the Formula and Unit of EMF?

The formula for the Electromotive Force is as follows:

E = V + Ir

In the formula, 

  • V is the voltage of the cell 
  • I is the current present throughout the circuit
  • r is the internal resistance of the cell
  • And E is the Electromotive force

Numerically, EMF is described as the number of Joules of energy supplied through the source upon each Coulomb to enable a unit electric charge to move across the circuit.

Volts = joules/coulombs

What are the Characteristics of EMF?

The following are the characteristics of EMF:

  • EMF is defined as the work done on a unit charge
  • Electromotive force is independent of circuit resistance
  • It remains constant 
  • Electric, magnetic and the gravitational field are caused due to EMF
  • E is used to represent the electromotive force
