A battery has an internal resistance of 0.75 ohm and an emf of 9 V. It is placed a cross a 5 ohm resistor and a 10 uF capacitor hooked up in parallel. a) after the capacitor has charged, what is the current through the resistor? b) what is the charge on the capacitor? c) if the battery is disconnected how long will it take the capacitor to reach one-third of its initial voltage?
