• question_answer Some electric bulbs are connected in series across a 220 V supply in a room. If one bulb is fused then remaining bulbs are connected again in series across the same supply. The illumination in the room will                  [J & K CET 2004] A)            Increase                                     B)            Decrease C)            Remains the same                    D)            Not continuous

$P=\frac{{{V}^{2}}}{R}$  ÞÞ $P\propto \frac{1}{R}$     (V - constant) \ When one bulb will fuse out resistance of the series combination will be reduced. Hence from ${{P}_{Consumed}}\propto \frac{1}{R}$ illumination will increase.
