R = 600 ohm,
L = 2 H,
C = 10 uF = 10⁻⁵ F
V = (50√2 sin 100t) volt
VL = __?

Frekuensi sudut
V = (50√2 sin 100t
V = Vₘ sin ωt
diperoleh
• Vₘ = 50√2 V
• ω = 100 rad/s

Reaktansi induktif
XL = ω L
XL = 100 • 2
XL = 200 ohm

Reaktansi kapasitif
XC = 1 / (ω C)
XC = 1 / (100 • 10⁻⁵)
XC = 1000 ohm

Impedansi
Z = √(R² + (XL - XC)²)
Z = √(600² + (200 - 1000)²)
Z = 1000 ohm

kuat arus maksimum
Vₘ = iₘ • Z
50√2 = iₘ • 1000
iₘ = (1/20)√2 A
iₑ = 1/20 A


tegangan induktor

maksimum
VLₘ = iₘ • XL
VLₘ = (1/20)√2 • 200
VLₘ = 10√2 V ✓

efektif
VLₑ = iₑ • XL
VLₑ = (1/20) • 200
VLₑ = 10 V ✓
