R = 9 Ω
XL = 28 Ω
XC = 12 Ω
V = 110 V
Z = __ ?
i = __ ?
Θ = ___ ?
cos Θ = __ ?
Impedansi
Z = √(R² + (XL - XC)²)
Z = √(9² + (28 - 16)²)
Z = √(9² + 12²)
Z= 15 Ω ← jwb
Kuat arus
V = i Z
110 = i · 15
i = 110/15 A ← jwb
sudut fase
tan Θ = (XL - XC) / R
tan Θ = (28 - 16) / 9
tan Θ = 12 / 9
Θ = 53° ← jwb
faktor daya
cos Θ = cos 53°
cos Θ = 0,6 ← jwb
Ok ?
