When an electric current is passed through a conductor, the conductor becomes hot after some time and produce heat. This happens due to the conversion of some electric energy passing through the conductor into heat energy. This effect of electric current is called...

The electric energy consumed by an electrical appliance is given by the product of its power and the time for which it is used i.e. Electrical energy = Power X time or, E = P X t The S.I. unit of...

When two or more resistors are connected across a common point so that same current flows through different paths they are said to be connected in parallel. Suppose three resistors R1, R2 and R3 are joined in parallel as shown in figure and let the potential...
