Question

Which of the following statements are correct for the RCcircuit shown? A) If S is in the position a for a longtime, the current through R approaches zero.
B) If S is in the position a for a long time, thecharge on C approaches zero.
C) If S is in the position a for a long time, thecurrent through R approaches E/R.
D) Right after S is moved to the position b,following a long time in the position a, the potentialacross C is nearly zero.
E) If S is in the position b for a long time, thecurrent through R approaches E/R.
F) After S is moved to b, it takes a time tau=RC, for the charge on C to drop to 1/e of itsinitial value.
G) After S is in the position b for a long time,the current through R becomes close to zero.

Explanation / Answer

answers are
If S is in the position a for a long time, thecurrent through R approaches E/R.
Right after S is moved to the position b,following a long time in the position a, the potentialacross C is nearly zero.
If S is in the position b for a long time,the current through R approaches E/R.
After S is moved to b, it takes a time tau=RC, for the charge on C to drop to 1/e of itsinitial value.
After S is in the position b for a longtime, the current through R becomes close to zero
