Time	Narration
00:01	Hello everyone. Welcome to this tutorial on Transient Response of circuits.
00:08	In this tutorial, we will study: Transient response of RC, RL and LCR circuits Under damped discharge of LCR circuit RC integration and Differentiation.
00:24	Here, I am using: ExpEYES version 3.1.0 Ubuntu Linux OS version 14.10.
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: Plot Step up and Step down voltage curves of RC circuit. Measure RC in milli seconds.
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: Charging of capacitor with constant current and Measure RC in milli seconds.
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 exponentially.
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: Plot Step up and Step down voltage curves of RL and Measure R/L.
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 i s =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 window 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 a square wave into a triangular wave.
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.
