EE 282 – Circuit I
Lab 9
RC circuits
Name ______________________________
Concepts: In this lab we will be learning about the transient characteristics of RC
circuits.
Equipment: Oscilloscope, NI elvis system, 1 resistor, 1 capacitor
The nominal (but not exact; you need to measure the actual) values of the resistors are:
R1 = 2.70 k? ?
C1 = 6.8nF?
?
Use the handheld multimeter to measure and record the actual values of the resistor.
R1 _________
Build the circuit on your breadboard and connect the elvis power supply as shown in figure
below.
XFG1
R1
2
2.7kO

C1
6.8nF
Vout
0
Use the oscilloscope channel 1 and channel 2 to observe both the input and output of the
RC voltage divider. Adjust the frequency so the capacitor just becomes fully charged.
Save a printout of the oscilloscope display and attach to the lab report.
Measure the time required to fully charge the capacitor.
(a) How many RC time constants are required to fill up the capacitor?
(b) The RC time constant is the amount of time it takes to charge a capacitor to 63.2% of
the final voltage. Use the cursors to find this time. Does the measured time match the
calculated time?
Time constant (RC) = _______
Number of RC to charge = _______________
Measured Time Constant = ________
Percent error = ___________________
Part 2: Change the circuit so the capacitor is in the resistor’s position and the resistor is
in the capacitor’s position. Adjust the frequency of the function generator until the
capacitor just becomes fully discharged. Measure the time required to fully discharge the
capacitor. How many RC time constants are required to empty the capacitor? Measure
the time to discharge to 36.8% of the original voltage. Does this time match the
calculated value?
RC = _______ Number of RC to charge = _______________
Measured Time Constant = ________
Percent error = ___________________

RC circuits
Equipment needed:
R1=2.7kO/2.2k?; C1=10nF; NIELVIS oscilloscope; NIELVIS Function generator
Part 1
Build the following circuit on your breadboard.
Or 2.2k?
Or 10nF
?
Use channel “0” of the Scope to measure input voltage waveform of the circuit and
channel “1” to measure output voltage (across the C1 capacitor) waveform of the
circuit.

Frequency: 1000Hz
Voltage peak to peak =2V
Square waveform
?
?
Hit run
Open NIELVIS Oscilloscope and observe waveforms.(make sure to hit enabled on channel 1
settings)
Save a printout of the oscilloscope display and attach to the lab report.
?
If you look at the waveforms from the oscilloscope you should get waveforms similar to the following
figure.

? Now let’s measure the total time required to fully charge the capacitor.
To measure the time difference we will use cursors in the oscilloscope.
? Move C1 cursor to the initial voltage and C2 cursor to the point that capacitor gets
charged on the blue waveform.
? Then look at the dT value shown in yellow color. That would be the total time it takes
for the capacitor to get fully charged.
(a) How many RC time constants are required to fill up the capacitor?
First, let’s calculate the time constant of this circuit.
Time constant of the circuit=? × ? =you would get the answer in seconds.

(b) Now we need to measure the time constant. To find the time constant we will take the
amount of time it takes to charge the capacitor 36.8% of the initial voltage (or 63.2%
of the final voltage)
? Initial voltage should be something close to 1V, since the amplitude is 1 V.
?
36.8
Then calculate 36.8 of initial voltage= 100 × 1? = 368??
We will again use cursors to measure the time difference (dT) between the initial
voltage (c1) and 36.8% of the initial voltage (c2)
Find error %
??????? ????? =
?????????? ???? ???????? – ???????? ???? ????????

Now change the circuit so the capacitor is in the resistor’s position and the resistor is in the capacitor
position. Adjust the frequency of the function generator until the capacitor just becomes fully
discharged. Do the same procedure as part 1.
?
Save a printout of the oscilloscope display and attach to the lab report.
