| 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 circuit'''s 

* '''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 curve'''s 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

|-
|06:21
|In this experiment, we will transform a square wave into a triangular wave.

|-
|07:05
|A triangular wave is generated. A square wave is transformed to a triangular wave when '''RC''' is integrated.
