Question 13
Original source text (the original panel preserves all diagram labels, tables and choices):
Wong has set up an electric circuit using six light bulbs, as shown in the diagram
below:
Assuming each bulb has the same resistance, which of the following statements
is CORRECT?
I. The current passing through bulb U will be greater than the current passing
through bulb Q because bulb U is directly connected in parallel with the power
source.
II. If bulb S burns out, bulb T will not light up because they are connected in
series in the same branch.
III. Bulb P will glow brighter than bulb S because bulb P is directly connected to
the power source.
IV. All the bulbs in the circuit will glow with the same brightness because they
all have the same resistance and are connected to the same power source.
A. I, II and III only C. II and IV only
B. I and II only D. Only IV
