A) Right after S is moved to position a, following a long time in the position b

Question

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

B) The longer S is kept in the position a, the higher is the energy stored in C.

C) If S is in the position a for a long time, the current through R approaches ?/R.

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

E) If S is in the position a for a long time, the charge on C approaches zero.

F) Right after S is moved to the position a, following a long time in the position b, the current through R is zero.

Which of the following statements are correct for the RC circuit shown? Select true or false for each statement. (? is the emf of the battery.) You may assume that when the switch is in position b for a long time, the capacitor is fully discharged (Q = 0). Right after S is moved to position a, following a long time in the position b, the current through R is ?/R. The longer S is kept in the position a, the higher is the energy stored in C. If S is in the position a for a long time, the current through R approaches ?/R. If S is in the position a for a long time, the current through R approaches zero. If S is in the position a for a long time, the charge on C approaches zero. Right after S is moved to the position a, following a long time in the position b, the current through R is zero.

Explanation / Answer

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