You have the following RC circuit: V=52V C=.1x10^-6 F and R= 3.1 Mohms. The circuit is initially uncharged. It is the allowed to charge. It is then left hooked up to the battery for a long time. Then it is allowed to discharge completely.
What is the value of the time constant?
What is the maximum charge in the capacitor?
At what time,after it began charging, is the voltage across the capacitor 35V?
At what time after it started discharging is its charge 40 percent of its maximum charge?
