Answer:
Xc= 17.267 Ω, Z= 415.5 Ω, I= 0.537 A
Explanation:
Em = 223 V
f= 300 Hz, R = 222 Ω, L = 147 mH, C = 23.1 μF
a)
Capacitive reactance = Xc=?
Xc= [tex]\frac{1}{2\pi fC}[/tex]
Xc=1/2pi *399*23.1*10^-6
Xc= 17.267 Ω
b).
Z=[tex]\sqrt{ R^2 + (Xl - Xc)^2}[/tex]
Xl= 2π * f * L
Xl= 2π * 399 * 147 * [tex]10^{-3}[/tex]
Xl= 368.5 Ω
Z=[tex]\sqrt{ R^2 + (Xl - Xc)^2}[/tex] = [tex]\sqrt{222^2 + (368.5 - 17.267)^2}[/tex]
Z= 415.5 Ω
c).
Current:
I= V / Z= Em / Z
I= 223/415.5
I= 0.537 A
