Question

Q5

- Assume the baɛɛery is ideal, and that the capacitor is initially Vicharged You have a 3000 -ohm resistor, a 10-mF Capacírur, and a 100-V battery You connect the battery resiston and capacitor in Series, and complece Q5 the cirde forming a loop, A How much time passes before the capacitor reaches 2/3 of max cheet? Blwhat is the magnitude of the current when the capacitor is at 213 ] How much charge is on the capacitor 10 seconds after the calauzor reaches 213 max charge?
