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...

The resistors can be combined in two ways to get the desired resistance. (1) Series Circuit (combination of resistors in series) (2) Parallel Circuit (Combination of resistors in parallel) When two or more resistances are connected end to end so that same current...

According to ohm’s law the current (I) flowing through a conductor is directly proportional to the potential difference (V) across the ends of the conductor, provided temperature of the conductor is kept constant, i.e. I V or V...
