Current \(I\) as a function of time \(t\) in a discharging LR circuit.
Current \(I\) as a function of time \(t\) in a discharging LR circuit.
A circuit containing a resistor of resistance \(R\) and an inductor of inductance \(L\) initially carries a steady-state current \(I_0\). At time \(t = 0\), the power source is bypassed, allowing the current to decay through the resistor as shown in the \(I(t)\) graph below. Which of the following claims correctly describes the magnitude of the potential difference \(|V_L|\) across the inductor as time progresses, based on the features of the graph?
