Question

Which of the following statements are true about the circuit drawn here?
figure
A. Bulbs, X, Y and Z are connected in parallel.
B. If bulb X fuses, bulbs Y and Z will not glow.
C. Bulbs X, Y and Z are connected in series.
D. The current has only one path to flow through this circuit.

(a) All are correct.
(b) A, B and D are correct.
(c) B, C and D are correct.
(d) A and B are correct.

Solution

(c) B, C and D are correct.
All the bulbs are connected in series; therefore, if one bulb gets fused, other bulbs will also not glow. Also, a series circuit has only one path for the electricity to follow.
