Physics electric circuit problem?

Question

a emf source, a resistor, and a capacitor are connected in a series circuit. when the capacitor becomes fully charged, and its potential drop equals that of the emf, what happens to the potential of the resistor?

Answer 1

The first guy was right.

Answer 2

If Thevenin was right, and I know he was, the sum of the voltages in a closed loop is zero.  So if the capacitor has all the voltage, then the resistor is left with none.  Vcap + Vres = EMF.

Answer 3

Current goes to zero. No voltage drop = no current.

Answer 4

Theoretically voltage acrosses resistor is zero,however as you do such experiment,you never obtain a zero volt acrossing the resistor. Because the capacitor always has a very very small leakage,therefore a very very small charging current continues to charge the capacitor to compensate the leakage.

The answer is:

Close to zero volt but never reach zero volt.
