Circuit with three identical resistors and a capacitor.
Circuit with three identical resistors and a capacitor.
A circuit consists of an ideal battery of voltage \(V_0\), an open switch \(S\), and three identical resistors of resistance \(R\), arranged as shown. Resistor \(R_1\) is in series with the battery, while resistors \(R_2\) and \(R_3\) form two parallel branches, with an uncharged capacitor of capacitance \(C\) connected in series with \(R_3\). At time \(t = 0\), switch \(S\) is closed. Which of the following graphs best represents the current \(I_2\) through resistor \(R_2\) as a function of time \(t\)?
