Various phenomena which are related to the presence and flow of electric charge come under electricity. Electric charge is a physical property of matter which causes the matter to experience a force when placed in an electromagnetic field. The flow of electric charge is called electric current. Resistance is an important property of matter and it explains the relative ease or difficulty by which electric current can pass through a matter. Ohm’s Law explains the relation between electric current and resistance. Resistances can be combined in two combinations, viz. series and parallel. Parallel combination is used for most of the purposes, while series combination is used for some special purposes.
