in matlab plz using Simulink

In order to simulate the movement of the circuit switch from B to A when Vr>5v, you will need a Switch Block and a MinMax Running Resettable Block (found in the Math Operations Library). You will need the MinMax Running Resettable Block so that when Vr exceeds 5v for the first time, it will maintain an output of 5v to the Switch block so that 0 volts is selected instead of Vs. 3. Define R, L, and Vs in the Matlab workspace. 4. Display the value of Vr in an oscilloscope from 0 to 2.0 seconds. 5. You will need to set the maximum step size to 0.001 second. 11.10 Problems 355 stant. Solve this differential equation symbolically for x(t). Also, determine symbolically the time t at which the infection rate dx/dt is maximum. 21. A resistor R(R=0.4) and an inductor L(L=0.08H) are connected as shown. Initially, the switch is connected to point A and there is no current in the circuit. At t=0 the switch is moved from A to B, such that the resistor and the inductor are connected to vS(vS=6V), and current starts flowing in the circuit. The switch remains connected to B until the voltage on the resistor reaches 5V. At that time (tBA) the switch is moved back to A. The current i in the circuit can be calculated from solving the differential equations: iR+Ldtdi=vS During the time from t=0 and until the time when the switch is moved back to A. iR+Ldtdi=0 From the time when the switch is moved back to A and on. The voltage across the resistor vR at any time is given by vR=iR
