Question

Which of the following statements are correct for the RC circuit shown? Select true or false for each statement. (E is the emf of the battery.)

A. Right after S is moved to the position b, following a long time in the position a, the current through R is E/R.

B. Right after S is moved to the position b, following a long time in the position a, the potential across C is close to E.
C. After S is moved to b, it takes a time tau=RC for the charge on C to drop to 1/e of its initial value.

D. The longer S is kept in the position a, the lower is the energy stored in C.

E. If S is in the position a for a long time, the current through R approaches zero.

F. The longer S is kept in the position a, the higher is the energy strored in C.
