RC Circuit Initial Current Estimation

Mark
< Prev
Next >

A capacitor discharges through a resistor. During the initial 0.12 s of discharge, a total of 3.6×10−33.6 \times 10^{-3} C of charge leaves the capacitor. The charge QQ remaining on the capacitor at time tt is described by the equation Q(t)=Q0e−t/RCQ(t) = Q_0 e^{-t/RC}. Without knowing the values for the time constant RCRC or the initial charge Q0Q_0, what is the best estimate for the initial current, I0I_0, in the circuit?

A

3.0 × 10^-2 A

B

1.5 × 10^-2 A

C

4.3 × 10^-4 A

D

3.0 × 10^-1 A
