RLC PARALLEL CIRCUIT (1)

RLC SERIES CIRCUIT
ОВЈЕСTIVE:
To get familiar with the measurement of voltage and phase shift in a series sinusoidal circuit.
THEORY:
For an RLC Series Circuit:
The total impedance of a series circuit (Zr) is equal to the sum of all impedances:
ZT = R +jXL -jXc
R
L
1ΚΩ
30mH
= R +j(XL - Xc)
+ VR -
+ V. -
Using phasor form:
E
4V 8Vpr//
Zr = R? +(XL-XS? Ztan
-1(XL-Xc
Ve 0.01µF
10KHZ
R
Where,
XL = 2nfL and Xc =
2nfC
The current (I) in a series circuit is calculated as follows
E
I =
The voltages VR, VL, and Vc are calculated using the current I
VR = IZR
where ZR= RZO°
VL = IZL
where ZL = XL Z90°
Vc = IZc
where ZC = XCZ-90°
EXPERIMENT PROCEDURE:
Connect the circuit shown above and use the oscilloscope to measure the variables shown in the
table below (for the current use the multimeter)
(NOTE: to measure a voltage using the oscilloscope, the voltage has to be connected to ground.
So in the circuit above, when you measure VL, you need to exchange the locations of the
inductor and the capacitor. The same thing with VR.
RESULTS:
VL(rms)
VR(rms)
OR
I (rms)
V (rms)
ASSIGNMENT:
1- Calculate I (magnitude and angle in rms) of the RLC series circuit using theoretical
equations (use Erms = 2.83VZ0°)
2- Use the calculated value of I to calculate Vc, VL, and VR (magnitude and angle) and
compare to the measured values in the table above.
