Question
The capacitor in an RC circuit(R = 100 , C = 45 uF) isinitially uncharged.
Find the charge on the capacitor in the circuit one timeconstant (r = RC) after the circuit is connected to a9.0-V battery. (answer q(r)=_____ uC) Find the current in the circuit one timeconstant (r = RC) after the circuit is connected to a 9.0-Vbattery. (answer I(r)=______ mA

Explanation / Answer
Time constant t = R CCharge on the capacitor Q = Qo ( 1- e -t/RC )
Qo = C V
Current in theresistance I = Io e -t/RC where Io = V / R
