Question

A. After S is in the position b for a long time, the current through R becomes close to zero.

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 .

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

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

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

F. Right after S is moved to the position b, following a long time in the position a, the potential across C is nearly zero.

G. If S is in the position b for a long time, the charge on C approaches CE.

Explanation / Answer

As mentioned, I am giving only correct option with explanation.

(A) Because all the charge on capacitor will discharge through the resister R and finally after long time it become zero.

(B) When the switch was connected to a, ciscuit was close and current was flowing and charging the capacitor untill it get completely charged. When the capacitor get completely charged, there wont be any current hence there will not potential drop across the resistor. All the potential come across the capacitor.

(D) Already explain in B
