In the circuit of Figure 7.1, let \(\mathrm{R}=0.125 \Omega ., \mathrm{L}=10 \mathrm{mH}\), and the source voltage is \(e(\mathrm{t})=151 \sin (377 \mathrm{t}+\alpha) \mathrm{V}\). Determine the current response after closing the switch for the following cases:

(a) no dc offset or

(b) maximum dc offset. Sketch the current waveform up to \(t=0.10 \mathrm{~s}\) corresponding to parts (a) and (b).
