An uncharged capacitor of capacitance \(C\) and a resistor of resistance \(R\) are connected in series with a periodic voltage source \(\varepsilon(t)\). The source voltage alternates between \(+V_0\) and \(0\) with period \(T\), where the half-period is much greater than the circuit time constant (\(T/2 \gg RC\)), such that \(\varepsilon(t) = +V_0\) for \(0 \le t < T/2\) and \(\varepsilon(t) = 0\) for \(T/2 \le t < T\). Which of the following graphs best represents the potential difference across the resistor, \(V_R(t)\), as a function of time over one full period \(0 \le t \le T\)?
