Distinction between EMF and Potential Difference
The main difference between EMF and potential difference is that the energy per unit charge exerted by an energy source is known as the EMF whereas the energy released when a unit quantity of electricity travels from one spot to another is known as the potential difference.
|The quantity of energy delivered to each coulomb of charge is known as the electromotive force.||One coulomb of charge expends a certain amount of energy, which is called the potential difference.|
|The unit of EMF is Volt.||The unit of potential difference is Volt.|
|It is independent of resistance.||It depends upon resistance between two points.|
|It is measured using an emf meter.||It is measured using a voltmeter.|
|The electric, gravitational, and magnetic fields are responsible for this.||The electric field is the sole source of potential difference.|
