Question
In the figure at the right is shown a circuit with two identical batteries and three identical resistors (bulbs). The batteries are shown so that the anode (positive terminal) is on the right of each battery. If one of these batteries were to be directly connected to one of these bulbs, it would light the bulb brightly.
For the following items, select the item that best completes the sentence and enter it in your answer sheet. If more than one answer is correct, give them all.
A. When the set of batteries and bulbs are connected as shown
all of the bulbs will be lit but they will not be equally bright.
you cannot tell which bulbs will be lit from the information given.
none of the bulbs will be lit.
all of the bulbs will be lit equally brightly.
only one of the bulbs will be lit.
B. The potential drop across bulb B
equals zero.is the same as that across bulb C.
is the same as that across bulb A.
is the same as that across one of the batteries.
cannot be determined from the information given.
is double that across one of the batteries.
C. The current through bulb C (Select all that apply.)
cannot be determined from the information given.equals zero.
is less than through either of the other bulbs.
is the same as through the other two bulbs.is the same as the current in battery I.
is the same as the current in battery II.
is greater than through either of the other bulbs.

Explanation / Answer
A) all bulbs will lit C will lit more than A,B (are in parallel so current will devide hence Power =I^2R will be lesser)
B)
The potential drop across bulb B is the same as that across bulb A. as both are connected parallel
C)
The current through bulb C
is the same as the current in battery II.
is greater than through either of the other bulbs.
