Answer:
(a)
No.
Reasons:
Let R be the resistance of each bulb, then total resistance in series =3R
In
series, current in each bulb is same.
So
current drawn by each bulb connected in series is one-third as compared to the
current in each bulb in parallel arrangement, so the bulbs connected in
parallel combination glow more brightly.
(b)
In series arrangement, if one bulb is fused; then current in the bulbs connected
in series will become zero, so bulbs will stop glowing. In parallel arrangement,
if one bulb is fused, the other two bulbs will continue to glow with same
brightness.
