RC Circuit Discharge Current
A capacitor of capacitance C is charged to a potential difference V₀ and subsequently discharged through a resistor R. The charge on the capacitor at time t is given by q(t) = CV₀e^(-t/RC). Which of the following expressions represents the current through the resistor at time t?
A
(CV₀/R)e^(-t/RC)
B
-(CV₀/RC)e^(-t/RC)
C
(V₀/R)e^(-t/RC)
D
-(V₀/RC)e^(-t/RC)
