Tegangan dan Arus Bolak - Balik

- Rangkaian R - L - C

R = 600 Ω

L = 1 H

C = 5 μC = 5 × 10⁻⁶ C

V = (100 sin 1000t) Volt

Vₘₐₖₛ = 100 V , ω = 1000 rad/s

P dis. = __ ?

Kita Cari XL :

XL = ωL

XL = 1000 × 1

XL = 1000 Ω

Kita Cari XC :

XC = 1/ωC

XC = 1 / (1000 × 5 × 10⁻⁶)

XC = 200 Ω

Kita Cari Impedansi (Z) :

\begin{gathered}Z = \sqrt{R^2 + (XL - XC)^2 } \\ Z = \sqrt{600^2 + (1000 - 200)^2} \\ Z = \sqrt{600^2 + 800^2}\end{gathered}

Z=

+(XL−XC)

+(1000−200)

Z = 1000 Ω

Kita Cari Iₘₐₖₛ :

Iₘₐₖₛ = Vₘₐₖₛ / Z

Iₘₐₖₛ = 100 / 1000

Iₘₐₖₛ = 0,1 A

Kita Cari Arus efektif (Iₑ) :

Iₑ = Iₘₐₖₛ / √2

Iₑ = 0,1 / √2

Iₑ = 0,05√2 A

Maka , P. dis :

P. dis = Iₑ²R

P. dis = (0,05√2)² × 600

P. dis = 3 Watt
