Homework Help: physics

Posted by Anonymous on Thursday, March 8, 2012 at 9:58pm.

A 9 V battery is connected in series with a 100 Ω resistor and 12F capacitor. The capacitor is initially uncharged. What is the capacitive time constant of the circuit? How much charge q(t) is in the capacitor after two time constants?. What is the limiting value of the charge on the capacitor? When the battery is disconnected and the capacitor is discharged, what is the current i(t) in the circuit after two time constants? What is the limiting value of the current? Draw the curves q(t) and i(t) as functions of time and label them appropriately.
