Question

In the circuit shown, when the switch $S$ is closed, then

• A. no charge flows through $S$
• B. charge flows from $A$ and $B$
• C. charge flows from $B$ and $A$
• D. charge flows initially from $A$ to $B$ and later from $B$ to $A$

Answer 1

The correct option is A no charge flows through $S$

For two conductors in series, their potential differences are proportional to their resistance. For two capacitors in series, their potential differences are inversely proportional to their capacitances. Hence Aand B are at the same potential and no charge will flow between them.
