09.36: For the RC circuit shown, the resistance is R = 0.10 R, the.p64ir :krlm rk 17kqi capacitance is C =5.0 F and the battery has voltage ξ=12 V. The capacitor is initially uncharged when:k rri7kr4qkp ml61i . 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 across the capacitor at that moment?
