Complete Response of a First Order RC Circuit


The figure below shows the complete response of a RC circuit to the input voltage

The complete response of the RC circuit is described by the equation

The values of the parameters A and B, as well as the values of the resistance R and capacitance C, can be changed using the scrollbars.


Suggestions:

  1. Set A=2 V, B=6 V, R=10 kOhms and C = 2 uF to see the circuit obtained by applying Thevenin's Theorem in Example 8.3-1.

  2. Set A=7.2 V, B=0.8 V, R=20 kOhms and C = 2 uF to see the circuit obtained by applying Thevenin's Theorem in Example 8.3-3.

  3. Set A=8 V, B=-4 V, R=2k || 4k= 1.33 kOhms and C = 0.5 uF to see the circuit obtained by applying Thevenin's Theorem in Problem 8.3-2.

  4. Set A=5.3 V, B=1.3 V, R=2 kOhms and C = 0.5 uF to see the circuit obtained by applying Thevenin's Theorem in Problem 8.3-10.

  5. Set A=10 V, R=10 kOhms and C = 2 uF. Vary B.

  6. Set B=10 V, R=10 kOhms and C = 2 uF. Vary A.

  7. Set A=1 V, B=10 V and R=20 kOhms. Vary C.

  8. Set A=10 V, B=1 V and C=1 uF. Vary R.

  9. Set A=-9 V, B=10 V and C=0.5 uF. Predict the value of R required to cause the capacitor voltage to be zero at time t=15 ms. Check this prediction using the scrollbars.

  10. Set A=7 V, B=-9 V and R=14.4 kOhms. Predict the value of C required to cause the capacitor voltage to be zero at time t=15 ms. Check this prediction using the scrollbars.
