A circuit contains a charged capacitor of capacitance \(C = 4.0 \text{ }\mu\text{F}\) that discharges through an unknown resistor \(R\). A student measures the potential difference \(V\) across the capacitor as a function of time \(t\) and constructs a graph of \(\ln(V/\text{1 V})\) versus \(t\), as shown. Based on the graph, what is the resistance \(R\) of the resistor?
