Charging and Discharging of capacitor

1#

09.36: For the RC circuit shown, the resistance is R = 0.10 R, the ty4w 0qbxv */ mmb /+6zdoni9kcapacitance is C =5.0 F and the battery has voltage ξ=12 V. The capacitor is initially uncharged when the switch S is closed at time t=0. At sometime later, the current in the circuit is 0.50 A. What is the magnitude of the voltage acro9z q6ybbwn ox/dm/m k+0 t4v*iss the capacitor at that moment?
