Problem: A capacitor with capacitance C is initially charged with charge q. At time t = 0, a switch is thrown to close the circuit connecting the capacitor in series with a resistor of resistance R. (Intro 1 figure). What is the current Io that flows through the resistor immediately after the switch is thrown?Express your answer in terms of any or all of the quantities, q, R, and C.

The charge stored on a capacitor, 

Q=CV

The capacitor has a capacitance, C, and a charge, q. The voltage across the capacitor will be,

V = Q / C = q / C
