- In the above circuit, the switch is open for a long time.i)The switch closes for 50 us. What is the current through the inductor? Also, what is the voltage at the output with respect to ground just before the switch open?ii) The switch closes. What is the maximum current the inductor will see?arrow_forwardIn the figure R, = 4.00 N, and R, = 1.00 N. The inductor is ideal. When the switch is opened after having been closed for a long time, the current in the inductor drops from 1.00 A to 0.250 A in 0.200 s. What is the inductance of the inductor in mH?
