$$L \fracd\hati_Ldt = V_g \hatd - \hatv_o$$ $$C \fracd\hatv_cdt = \hati_L - \frac\hatv_oR$$
The problem sets compiled by Andrés Barrado and Javier Pleite serve a critical function in engineering education. They force the student to look beyond the ideal switch and consider: $$L \fracd\hati_Ldt = V_g \hatd - \hatv_o$$ $$C
