In an RC circuit connected to a constant voltage source V0, what are the expressions for the capacitor voltage Vc(t) and the current i(t) after connection?

• A. Vc(t) = V0 e^{-t/RC}; i(t) = -(V0/R) e^{-t/RC}
• B. Vc(t) = V0; i(t) = 0
• C. Vc(t) = V0 (1 - e^{-t/RC}); i(t) = (V0/R) e^{-t/RC}
• D. Vc(t) = V0 (1 + e^{-t/RC}); i(t) = (V0/R) e^{-t/RC}

Answer: (C)
