Problem

A circuit contains three capacitors. Node A is connected to one plate of

C_1

and one plate of

C_2

. The other plates of

C_1

and

C_2

meet at node B. From node B, a single capacitor

C_3

connects to node C, which is attached to the negative terminal of a battery. Which pair of capacitors must always have the same potential difference at every instant? (a)

C_1

and

C_3

(b)

C_2

and

C_3

(c)

C_1

and

C_2

(d) None of the pairs always share the same potential difference
