| 00:01 | Hello everyone.Welcome to this tutorial on Transient Response of circuits. |
| 00:08 | In this tutorial we will study:
|
| 00:24 | Here I am using,
|
| 00:33 | To follow this tutorial, you should be familiar with:
ExpEYES Junior interface.If not, for relevant tutorials, please visit our website. |
| 00:44 | Let's first define transient Response of a circuit. |
| 00:49 | Transient Response is, how a circuit responds to stored energy in capacitors or inductors.
The stored energy in a capacitor or an inductor, can be dissipated by a resistor. |
| 01:03 | Now we will demonstrate transient Response of RC circuit. |
| 01:07 | In this experiment we will,
|
| 01:18 | To perform this experiment, OD1 is connected to A1 through 1K resistor. |
| 01:24 | 1uF(one micro farad) capacitor is connected between A1 and ground(GND).
This is the circuit diagram. |
| 01:34 | Let's see the result on the Plot window. |
| 01:36 | On the Plot window,click on EXPERIMENTS button.Select RC Circuit. |
| 01:43 | Transient response of RC Circuit and Schematic windows open.
Schematic window shows RC Circuit Transient. |
| 01:52 | On the Transient response of RC Circuit window, click on 0 to 5V STEP button.
Step up voltage curve is displayed. |
| 02:03 | Then click on 5 to 0V STEP button.Step down voltage curve is displayed. |
| 02:11 | Click on Calculate RC button.RC =1.14 msec is displayed. |
| 02:20 | Click on Clear button to clear the window. |
| 02:24 | Click on CC Charge button.A horizontal trace is seen at 4.5 volts. |
| 02:31 | Next we will show:
|
| 02:41 | In the circuit we will connect 1K resistor to CCS instead of OD1.This is the circuit diagram. |
| 02:51 | Click on CLEAR button to clear the window. |
| 02:55 | Click on CC Charge button.Voltage across the capacitor rises ex-ponentially. |
| 03:03 | Click on Calculate RC button.Value of RC= 5.81 mSec is displayed. |
| 03:12 | Now we will demonstrate transient Response of RL circuit. |
| 03:17 | In this experiment we will,
|
| 03:26 | In this experiment IN1 is connected to OD1.
OD1 is connected to A1 through 1K resistor. A1 is connected to GND through a coil. |
| 03:38 | This is the circuit diagram. |
| 03:41 | Let's see the result on the Plot window. |
| 03:44 | On the Plot window, click on EXPERIMENTS button.Select RL Circuit. |
| 03:51 | Transient response of RL Circuit and Schematic windows open.
Schematic window shows RL Circuit Transient. |
| 04:02 | On the Transient response of RL Circuit window, click on 0 to 5V STEP button.
Step up voltage curve is displayed. |
| 04:12 | Click on 5 to 0V STEP button.Step down voltage curve is displayed. |
| 04:20 | Click on Calculate R/L button to display the values. |
| 04:26 | L/R value is =0.083mSec(milli second).
Rind value is =529 Ohm. |
| 04:35 | Inductor value is =127.6mH(milli henry).
Here R is resistance L is inductance and Rind is resistance of the inductor. |
| 04:50 | As an assignment,Plot voltage curves of RL circuit using two coils connected in series. |
| 04:57 | Now we will show under damped discharge of LCR circuit. |
| 05:02 | In this experiment, OD1 is connected to A1 through a coil. |
| 05:07 | A1 is connected to GND through 0.1uF(0.1 micro farad) capacitance.This is the circuit diagram. |
| 05:15 | Let's see the result on the Plot window. |
| 05:18 | On the Plot window, click on EXPERIMENTS button.Select RLC Discharge. |
| 05:25 | EYES Junior: RLC Discharge and Schematic windows open.Schematic window shows RLC Circuit Transient. |
| 05:35 | On the EYES Junior: RLC Discharge window, click on 5->0V STEP button.Step down voltage curve is displayed. |
| 05:45 | Move the mS/div slider and click on 5->0V STEP button.Under damped discharge curve is displayed. |
| 05:55 | Click on FIT button to display the values.
Resonant Frequency=1.38 KHz and Damping = 0.300 |
| 06:08 | As an assignment,
Plot over damped discharge of LCR circuit using a 2K resistor.This is the circuit diagram. |
| 06:18 | Now we will demonstrate RC integration. |
| 06:21 | In this experiment we will transform,
|
| 06:28 | Here SQR2 is connected to A1 through 1K resistor. This is the circuit diagram. |
| 06:34 | Let's see the result on the Plot window. |
| 06:38 | On the Plot window set SQR2 to 1000 Hz.Click on SQR2 check box. |
| 06:45 | Move the frequency slider. |
| 06:48 | Move the mSec/div slider to adjust the wave. A square wave is generated. |
| 06:56 | In the same connection,Connect A1 to GND through 1uF(one micro farad) capacitor.This is the circuit diagram. |
| 07:05 | A triangular wave is generated.A square wave is transformed to a triangular wave when RC is integrated. |
| 07:14 | Click on XMG button to show the Grace plot of the triangular wave. |
| 07:20 | Now we will demonstrate RC differentiation. |
| 07:24 | In this experiment we will transform a square wave to a narrow spikes wave. |
