# Complete Response of a First Order RL Circuit

The figure below shows the complete response of a RL circuit to the input voltage The complete response of the RL circuit is described by the equation The values of the parameters A and B, as well as the values of the resistance R and inductance L, can be changed using the scrollbars.

Suggestions:

1. Set A=0 mA, B=4 mA, R=1000 Ohms and L = 5 mH to see the circuit obtained by applying Thevenin's Theorem in Example 8.3-2.

2. Set A=40 mA, B=20 mA, R=200 Ohms and L = 5 mH. to see the circuit obtained by applying Thevenin's Theorem in Example 8.3-4.

3. Set A=10 mA, R=1000 Ohms and L = 20 mH. Vary B.

4. Set B=10 mA, R=1000 Ohms and L = 20 mH. Vary A.

5. Set A=9 mA, B=9 mA and R=1000 Ohms. Vary L.

6. Set A=-9 mA, B=-9 mA and L = 2 mH. Vary R.

7. Set A = 7 mA, B = -8 mA and R = 4400 Ohms. Predict the value of L required to cause the inductor current to be zero at time t = 20 us. Check this prediction using the scrollbars.

8. Set A = 3 mA, B = -5 mA and L = 85 mH. Predict the value of R required to cause the inductor current to be zero at time t = 15 us. Check this prediction using the scrollbars.
