LAB # 1 MULTISIM PRACTICE Objectives At the end of this lab, the student will be able to: 1-
Create basic circuits in Multisim. 2-
Incorporate Virtual Instruments to the design. 3-
Compare calculated values with measured values. 4-
Open and save files in Multisim. Procedure: Exercise 1 – Series circuit 1. Create the following circuit in Multisim Fig. 1
2 2
Verify with calculations the displayed values of U1, PR1, PR2 and PR3. Note that PR2 is a differential probe which measures the voltage drop across R3. Enter your calculations below: U1=240/(1k+1.5k+2.2k+0.5k)=46.2mA PR1=240-(46mA*1k)=194 V PR2=240-
(46mA*1k)- (46mA*1.5k)-
(46mA*0.5k)=102 PR3=(46mA)2*0.5k=1.06 W

3 3.
Adjust the increment steps of R2 to 10 % (to access the configuration screen double-click on the symbol of R2). NOTE: (the display is a % of 1 kΩ i.e 10% of 1kΩ= 100 Ω) 4.
Change the setting of R2 until its power dissipation (measured by PR2) is maximum. What is its value? Explain why (hint: review theorems from EET-117 Theory 1). Exercise 3 – RC circuit analysis- Oscilloscope .
The power dissipation is high when the resistance value is at 60% i.e 600 Ω. According to theory P=VI ,the circuit is in series so they have same current flowing and the voltage drop depends on I and R ; if I is same than it depends on R. Since they are in series when and if there is only two resistor the power dissipation is high when they have same value.

Create the following circuit in Multisim. In this circuit, you can observe in an oscilloscope the charge and discharge function of a capacitor. Use CLOCK_VOLTAGE as the source Fig. 3 The voltage source in this circuit is a square waveform with a frequency of 500 Hz and an amplitude voltage of 5 V. The square wave provides ON-OFF action but unlike a single switch, it provides a discharge path back through the generator when the wave drops back to zero. In Multisim the voltage source V1 is called “Clock Voltage” and can be found in: Place -> Components -> Group Sources -> Signal Voltage Sources ->Clock Voltage The oscilloscope selected is Tektronix. More information available in the Multisim Manual http://www.ni.com/pdf/manuals/374483d.pdf 2.
Calculate the time constant of this circuit and the total time it takes for the capacitor to be fully charged. Enter your calculation below.
5 Time constant T
=10nf*15kΩ =150µs
Time to fully charge
= 150 µs * 5= 750 µs
3.
To activate the oscilloscope display, double-click on the oscilloscope icon. Adjust your vertical and horizontal settings as indicated in Fig. 3 (2 V/div and 200 µs/div) The oscilloscope controls are activated by left-clicking with the mouse on the particular button. To display the wave-form press the RUN/STOP button on the upper right and then the SINGLE SEQ to stabilize the waveform. 4.
By observing the displayed waveform calculate (must show the steps): a)
The period. b)
The time it takes for the capacitor to be fully charged (approximately). a) Period = 1 cycle=10 division = 200 µs* 10 = 2ms b) Time= 5 division = 200 µs *5 = 1ms

6 Exercise 4 – Function Generator- Oscilloscope practice
1.
Create the following circuit in Multisim. Fig. 4 The Function Generator in this circuit will provide a sinusoidal waveform that will be displayed on the oscilloscope screen. In above Fig. 4, the waveform has a Vp of 5 V and a frequency of 2 kHz. The vertical was adjusted to 2 V/div (the value is displayed on the bottom of the screen as CH1 2V). The horizontal was adjusted to 100 µs/div (value is displayed on the bottom of the screen as M 100 µs), the period of the waveform is T=1/f=1/2 kHz= 500 µs.

Adjust the Function Generator for the following values of amplitude and frequency of a sinewave and adjust the vertical and horizontal settings of the oscilloscope to be able to display a waveform with a large excursion in both axes. Calculate the period for each frequency and enter it in Table 1 Save each of the settings in a different file as indicated in the File Label column Amplitude Frequency Period File Label 1 Vp 5 kHz Enter.

Conclusion: The conclusion
summarizes important points of the laboratory work. You must
analyze the examples to add emphasis to significant points. You must also
include features and-or things you done/benefits of a particular procedure, instrument, component or circuit directly related to the experiment. In this lab, we were able to create and analyze the circuit in Multisim and able to compare that value with calculations.
