ELECTROMOTIVE FORCE – EMF:
To make use of electricity by provision of an electric current, the potential different must be maintained. That is, the positive and negative charge must be continuously replenished. A cell (or battery) uses chemical energy to maintain the potential difference.
Another device used for this purpose is the generator, which uses electro-mechanical energy to maintain the potential difference. The potential difference across the terminals of the source (cell, battery or generator) when it is not supplying current, is called Electromotive Force (emf), since this is a measure of the force available to push electrons around the circuit. In a circuit with a current flowing, the potential difference across the terminals of the source is always less than the emf and is referred to as the terminal voltage.

Q. What is the longest lasting synthetic periodic element? Answer:- A excellent candidate would be curium 247 (247Cm) which has a half-life of 1.56 × 107 year
The property of liquids (or gases) by virtue of which a backward dragging force (viscous drag) acts tangentially on the layers of the liquid in motion and it tries to stop the moti
Motion of an object in a straight line is called one dimensional motion. The location of a particle in one dimensional motion can be explained by only one variable (say x). For a p
