The following figure illustrates a relay circuit. The switch "S" activates and deactivates the relay (the electromechanical relay is modelled using a series connected RL load). To activate the relay a minimum current of 25mA is necessary (i.e. it will be deactivated if the current falls below 25mA). Parameters of the relay are given as: RR10092 and LR=200μH. To protect the Switch "S" a resistor RF1009 is placed parallel to the relay. Relay model 5V S I A) After being open for a sufficiently long time, the switch "S" is closed at t=0 and then opened at t=10μs. Please compute and sketch the voltage across the switch from t=5μs to t=15μs.
