Circuits for the discharge of the inductor in Scenario 1 and Scenario 2.
Circuits for the discharge of the inductor in Scenario 1 and Scenario 2.
An ideal inductor with inductance \(L\) carries an initial steady current \(I_0\). In Scenario 1, the inductor is disconnected from its power supply and allowed to discharge through two resistors with resistances \(R_1 = R\) and \(R_2 = 3R\) connected in series. In Scenario 2, the same inductor carrying the same initial current \(I_0\) is allowed to discharge through the two resistors connected in parallel. What is the ratio \(\Delta E_{1,\text{parallel}} / \Delta E_{1,\text{series}}\) of the total thermal energy dissipated in resistor \(R_1\) in Scenario 2 to that in Scenario 1 after all current has decayed to zero?
