Given that the voltage across the capacitor as a function of time is V(t)=q0Ce−t/(ROC)V(t)=q0Ce−t/(RC), what is the current I(t) flowing through the resistor as a function of time (for t>0t>0)? It might be helpful to look again at Part A of this problem. Express your answer in terms of ttt and any quantities given in the problem introduction.

Explanation:

If the voltage across a capacitor is given by

then by definition of the capacitance (C = Q/V), the charge on the capacitor is

Now we can relate the charge on the capacitor to the current through the capacitor by

Since this is a closed current with capacitor and resistor are connected in series, the current through the capacitor is equal to that of resistor.

the answer is b
