Vedclass · Answer

(A) The power consumed by a series circuit is given by $P = \frac{V^2}{R_{eq}}$,where $R_{eq}$ is the equivalent resistance of the circuit.Since the supply voltage $V$ is constant,$P \propto \frac{1}{R_{eq}}$.When one bulb is removed from the series combination,the total equivalent resistance $R_{eq}$ of the circuit decreases.Because $P$ is inversely proportional to $R_{eq}$,a decrease in resistance leads to an increase in the total power consumed by the remaining bulbs.Therefore,the brightness in the room will increase.

Some bulbs are connected in series to a $220\, V$ supply. If one bulb gets fused and the remaining bulbs are reconnected in series to the same supply,the brightness in the room will:
