Resistances are said to be in series, if the same current is flowing through each resistor when some potential difference is applied across the combination. Here the resistors are connected end to end with one another. The equivalent resistance of a number of resistors connected in series is equal to the sum of individual resistances.
Resistances are said to be connected in parallel if potential difference across each of them is the same and is equal to the applied potential difference. Here one end of all the resistors is coonnected to one point and other end of all the resistors to another point. The reciprocal of equivalent resistance of a no. of resistors connected in parallel is equal to the sum of the reciprocals of indivdual resistances.
