P2. [10 points] The circuit at right has & = 10V, R1 = R2 = 100, and L = 1.OH. R1 a) [1 point] After the switch has been closed for a long time, what is the current through the inductor? R2 a b C M mm b) [2 points] Now the switch is opened. Immediately after it is opened, is the voltage at point b higher, lower, or the same as the voltage at point c? c) [1 point] Immediately after the switch is opened, what is the current across the inductor? d) [1 point] Immediately after the switch is opened, what is the voltage across R1? e) [1 point] Immediately after the switch is opened, what is the voltage across the inductor? f) [4 points] What is the current through the inductor 0.2 seconds after the switch is opened
