Electric power is defined as the rate at which electrical energy is consumed in an electrical circuit. Electric power is given as:-
Where V is the potential difference
(i) When two bulbs rated
and
are connected in series, the current is the same through each bulb.
If
and
be the resistances of two bulbs, then effective resistance of the circuit is,
Using,
we have,
We have given that :-
Therefore -
Thus, the effective power when two bulbs are connected in series is
(ii) When two bulbs rated
and
are connected in parallel.
using the relation of parallel connection, we have
Thus,
given :
Thus,
Therefore, the effective power or power (dissipated) when two bulbs are connected in parallel is
