In the figure below, all bulbs and batteries are ideal and identical. Which of the following statement(s) is (are) correct? [Select all that are correct]

Figure a:

l--------(~A)-----------l

l l

l l

+/- (~B)

l l

l------------------------l

where +/- is the battery and ~A is lightbulb A and ~B is lightbulb B

(its a series circit with A and B)

Figure b

l--------(~A)-----------l----------------------]

l l l

l l l

+/- (~B) (~C)

l l l

l------------------------l-----------------------l

(Same as above but now they add circuit C on the outside which is parallel)

Bulb A is in parallel with Bulb B in (a)

In (b) Bulb A is in parallel with Bulb B

Bulb B is in parallel with Bulb C in (b)

In (b) Bulb A is in neither series or parallel with Bulb B

Bulbs B and C are connected in series in (b)

Bulb A is in series with Bulb B in (a)

The effective resistance of Bulbs A and B in (a) is less than the effective resistance of Bulbs A, B, and C in (b)

The effective resistance of Bulbs A and B in (a) is greater than the effective resistance of Bulbs A, B, and C in (b)

The resistance of Bulb A is greater than the effective resistance of Bulbs B and C in (b)

The effective resistance of Bulbs A and B in (a) is equal to the effective resistance of Bulbs A, B, and C in (b)

Bulb A is brighter than Bulb B in (a)

In (b) Bulb A is in series with Bulb B
