Question
Advanced lab students are learning to use phasor diagrams to analyze RLC series circuits. They are given the following phasor diagram, and they are told that the AC power source has a frequency of 60.0 Hz and the resistor has a resistance of 90.5 0.
Four vectors and a directional arrow are positioned
on a coordinate plane. All vectors begin at the origin.
In counterclockwise order, starting from the bottom:
vector labeled AV = 15.0 V points down along the
vertical axis; a second vector labeled AVR
= 20.0 V
points to the right along the horizontal axis; a third
vector labeled AV.
forming an angle of o with the horizontal axis; and a
fourth vector labeled AV, = 25.0 V points up along
Vmax points up and to the right
the vertical axis. A dashed line indicates that the
horizontal component of AVy equals the value of
AV.. A curved arrow pointing counterclockwise is
labeled w.
The students are then asked to determine the following.
(a) the maximum voltage AVay (in V) across the series RLC combination
V
(b) the phase angle o (in degrees)
(c) the maximum current (in A) in the circuit
(d) the total impedance (in n) of the circuit
Ω
(e) the capacitance (in µF)
uF
(f) the inductance (in H)
H
(9) the average power (in W) delivered to the circuit
w
