APFIVE RC Circuit Initial Current Estimation
A capacitor with unknown capacitance discharges through a resistor. Over a time interval of 0.12 seconds, a total charge of $$3.6 \times 10^{-3}$$ C exits the capacitor. The discharge follows $$Q(t) = Q_0 e^{-t/RC}$$, where $$Q_0$$ is the initial charge. Given no information about the time constant $$RC$$ or $$Q_0$$, what is the best estimate for the initial current through the resistor at $$t = 0$$, $$I_0$$?
