A series circuit consists of three identical lamps connected to a battery as shown in the figure. The switch S, originally open, is closed.
(i) What then happens to the brightness of lamp B?
(a) It increases.
(b) It decreases somewhat.
(c) It does not change.
(d) It drops to zero.
For parts (ii) to (vi), choose from the same possibilities (a) through (d).
(ii) What happens to the brightness of lamp C?
(iii) What happens to the current in the battery?
(iv) What happens to the potential difference across lamp A?
(v) What happens to the potential difference across lamp C?
(vi) What happens to the total power delivered to the lamps by the battery?
