Answer 1

LISTRIK DINAMIS

• Rangkaian Arus Searah

a][ Hambatan total

Hambatan R2, R3 dan R4 tersusun paralel.

1/Rp = 1/R2 + 1/R3 + 1/R4

1/Rp = 1/2 + 1/4 + 1/4

1/Rp = (2+1+1) / 4

Rp = 1 ohm

Hambatan R1 dan Rp tersusun seri

R = R1 + Rp

R = 1 + 1

R = 2 ohm ✔️

b][ Kuat arus

V = i R

i = V / R

i = 20 / 2

i = 10 A

i1 = i = 10 A ✔️

Vp = i Rp

Vp = 10 • 1

Vp = 10 V

i2 = Vp / R2

i2 = 10 / 2 = 5 A ✔️

i3 = Vp / R3

i3 = 10 / 4 = 2,5 A ✔️

i4 = Vp / R4

i4 = 10 / 4 = 2,5 A ✔️

c][ Energi pada R4

W4 = i4² R4 t

W4 = 2,5² • 4 • 1

W4 = 25 J ✔️
