Diket :Vef = 100 V
f = 60 Hz ---> ω = 2•π•f = 120π rad/s
R = 10 ohm
L = 26,5 mH
C = 106 μF
VL =. __?
Jawab :
Reaktansi Induktif
XL = ω•L
XL = 120π•26,5 μ ohm
XL = 3180•π m ohm
XL = 9985,2 x 10^-3 ohm
XL = 9,9852 ohm
Reaktansi kapasitif
XC = 1/ω•C
XC = 1/120π•106•10^-6
XC = 10^6 / 12720•π
XC = 10^6 / 39940,8
XC = 25,04 ohm
Impedansi
----------------
Z = √R² + (XL - XC)²
Z = √10² + (9,9852 - 25,04)²
Z = √(100 + (−15,0548)²
Z = √(100 + 226.64700304)
Z = 18,07 ohm
Arus efektif
I ef = V ef / Z
Ief = 100 / 18,07
Ief = 5,53 ampere
Tegangan Induktif
VL = Ief • XL
VL = 5,53 • 9,9852
VL = 55,22 volt
