In Fig. 30.11 switch S1 is closed while switch S2 is kept

QUESTION:

In Fig.  switch \(S_{1}\) is closed while switch \(S_{2}\) is kept open. The inductance is , the resistance is \(R=-48.0 \Omega\), and the emf of the battery is . At time  after \(S_{1}\) is closed, the current in the circuit is increasing at a rate of \(d i / d t=7.20 \mathrm{~A} / \mathrm{s}\). At this instant what is \(V_{a b}\), the voltage across the resistor?
