09.36: For the RC circuit shown, the resistance is R = 0.10 R, the capacitang rsp.qaa w2d48 ;fni 6atl9s.l1ofj zw4g3a8ce 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 0.5dito swgaf.4 .rfqg 2s84pawl3az1l 6a;98nj0 A. What is the magnitude of the voltage across the capacitor at that moment?
