What is the difference between potential difference and electromotive force?
Potential Difference
- Potential difference (PD) is the work done in moving a unit charge against the electric field between two specific points in the circuit.
- Potential difference can also be defined as the work done per unit charge to move a charge between the negative and the positive terminal of the battery
- The potential difference is applicable to magnetic, gravitational, and electric fields.
- SI unit of potential difference is volt (V).
Electromotive Force
- Electromotive force is the total voltage in an electric circuit generated by the source or battery.
- It is not a physical or a mechanical force.
- EMF is the energy required to move a unit positive charge from the negative terminal of the battery to the positive terminal when the circuit is open (open circuit means a discontinuous circuit wherein there is no flow of current)
- This is applicable only to an electrical field.
- Its SI unit is also volt (V).
