EMF AND POTENTIAL DIFFERENCE

Emf and potential difference

Emf :

We have already learnt that the rate of transfer or flow of electric charge is known as current and the force that is used to transfer this electric charge is known as Emf.
Emf in general is abbreviated as Electro motive force.
The units of this Electro motive force is Volts.

Potential difference :

Volt is the potential difference between two points of a conductor.
In general the potential at one end of a conductor is positive and the potential at the other end will be negative.
The difference in volts between this positive and negative ends is known as the Potential difference of the conductor.

WHAT'S THE DIFFERENCE BETWEEN CAPACITOR AND INDUCTOR ?

Do you know this???? We know that a capacitor is more or less a battery which store energy and coming to an inductor it is also a device which stores the energy but what's the difference??????? Come lets know... CAPACITOR is a device which stores only electrical energy in the form of POTENTIAL ENERGY. And, INDUCTOR is a device which stores Magnetic energy in the form of KINETIC ENERGY.
