Relation and functions in Maths In mathematics, a relation is a set of ordered pairs (a, b), where a and b are elements of a set. The set of all first elements (a) of the ordered pairs is called the domain of the relation, and the set of all second elements (b) is called the range. A function is a s...

Electrostatics and Electric Field Electric charges and fields Electric charges is of two types positive and negative loss of electrons gives positive charge and gain of electrons gives negative charge to a body SI unit of charge is Coulomb Dimensional formula is [AT] Quantization of charge The charg...
Magnetic Effects of Current Magnetic field-- In 1820 O rested observed that a compass needle shows deflection when brought near a current carrying wire this means electric current gives rise to magnetism - This law gives magnitude of magnetic field at any point due to current carrying conductor acco...
