When appliances of power P1, P2, P3…Pn are connected in series with a voltage source, the effective power consumed Peffective is given by:
Consider the following electric circuit in which the electric bulbs of power rating 60W each are connected in series with the voltage source 220 V.
Here the bulbs are connected in series. The effective power consumed is:
In series connections bulbs share the power.Therefore each bulb will light up with power = 20 W.
Total power used = 20×3 =60 W
