Week 3 Video Lecture – Multisim Single Frequency Analysis
Consider the circuit below:
For the circuit above, determine the following (express all answers in phasor form):
XC
Zeq
IT
R1
IC1
Construct the circuit with MultiSIM using a 5% tolerance for the resistor and the capacitor. Adjust the frequency according to the table below and obtain measurements from MultiSIM using AC Analysis and express in polar form.
Frequency IT IR1 IC1
100 Hz
500 Hz
1000 Hz
1500 Hz
10000 Hz
20000 Hz
Discuss the following:
Describe the relationship between the frequency and IT.
What effect does frequency have on Zeq?
How could the circuit be modified to bring the phase angle closer to 0○?
How could the circuit be modified to bring the phase angle closer to -90○?
Include all calculations, screenshots of measurements, the table results of part 3 and the answers to parts 2 and 4 in a word processing document and submit as EE115W3LabYourGID.docx, or an equivalent word processing file extension.
