Question

Which of the following statements are correct for the RC circuit shown? If S is in the position b for a long time, then right after S is moved to the position a, the current through R is /R. If S is in the position b for a long time, the charge on C approaches C . If S is in the position a for a long time, then right after S is moved to the position b, the potential across C is nearly zero. If S is in the position a for a long time, then right after S is moved to the position b, the current through R is zero. If S is in the position a for a long time, the current through R approaches /R.

Explanation / Answer

A) is correct as while connected through B for long time capacitor discharges to 0 V if there were any charge on it,then 0 V capacitor is connected to e by a charging resistance R.initially C will act like short ckt so current i=e/R
