What is the applied voltage for the circuit in the figure
below? Given; 60 Hz, Er = 118V, Ec = 209V
Eapp = square root of 118^2 + 209^2
=square root of 13,924 + 43681
=square root of 57,605
240 - Answers-120 volts
208 volts
-240 volts
327 volts
What is the capacitive reactance of a series RC circuit
containing a 100uF and a 200uF capacitor when supplied
by 500 Hertz power?
Ct = C1 + C2
Xc = 1/2pi (500) (300)
,2|Page
= .28 (150,000)
= ,000
=0.0000011 - Answers--1.1 microohms
3.0 microohms
4.8 Ohms
5.2 Ohms
What is the power factor for the circuit in the figure below?
Given; R = 150Ohms, C = 10uF, Eapp = 120Volts, It =
393mA, 60Hz
Xc = pi (60) (.00001)
=1/ 6.28 (.0006)
=263.16
Z = square root of R^2 + Xc^2
= square root of 150^2 + 263.16^2
= square root of 22,500 + 69,253.19
=square root of 91,753.19
=302.9
cos0= R / Z
=.9

If the frequency is increased in a series RL circuit, the
current will ____ - Answers--decrease
increase
increase proportionally with the frequency
remain the same
In general, when either the resistance or the inductive
reactance in a circuit is ______ the other, the smaller
value can be ignored. - Answers-half as much as
-ten times greater than
three times as great as
twice as great as
