Calculating the impedance of the circuit-
XL = 2pifL = (2)(3.14)(60)(0.15)
= 56.55 ohm
XC = =
= 106.10 ohm
R = 100 ohm
Total Impedance(Z) = (R2 + (XL - XC)2)0.5
Z = (10000 + 2455.2025)0.5
= 111.6 ohm
(i). Current in the circuit(I)-
I = VS/Z
=
= 1.97 A, 60 Hz
(ii). Power dissipated(P) in series LCR circuit is-
P =
=
= 388.59 W
(iii). Power factor = R/|Z|
cos =
= 0.896
