Answer :

(a) The bulbs which are in parallel connection will glow with more brightness than with series connection bulbs because in parallel connection, bulbs are connected with the same source. So, power in each bulb will be:

P = V2 /2R whereas in series Power through each bulb will be P= V2 /9R Therefore, bulbs in parallel connection will glow more.

(b) If one bulb in series circuit is fused then all the bulbs in the series circuit will get fused but in cause of parallel circuit, if one bulb fused the other two fused will continue to glow because in case of series circuit, same amount of current is distributed whereas in case of parallel circuit, the current is divided among electrical gadgets and is therefore, each bulb has different value of resistance and requires different current to operate.
