6. A series combination of a 1.04 mF capacitor and a resistor are connected to a 205 V battery. After 2.12 s, the voltage across the capacitor is 62.0 V. (a) What is the time constant of this RC circuit? (b) If at that four second mark the battery is subsequently removed and the capacitor is allowed to discharge through the resistor then how many excess electrons will remain on the capacitor at the seven second mark?
