Aseries circuit has an impedance of 62.0 ω and a power factor of 0.720 at a frequency of 47.0 hz . the source voltage lags the current. part a what circuit element, an inductor or a capacitor, should be placed in series with the circuit to raise its power factor? a. inductor b. capacitorpart b what size element will raise the power factor to unity? l =

L = 0.108 H

Explanation:

given,

impedance in the series circuit(Z) = 62 Ω

Power factor = 0.720

frequency = 47 Hz

A) Inductor will be placed in series so, that circuit raises to its power factor.

B)  Using expression of power factor

          R = 44.64 N

Source voltage lags since it is capacitive element, Capacitive reactant can is given by

Power factor is unity

           R' = Z'

impedence

Inductive reactance

L = 0.108 H

i believe the answer is a hope it and is correct
