LISTRIK DINAMIS

▶ Rangkaian Resistor

Perhatikan gambar!

Selisih kuat arus listrik (I) yang mengalir melalui rangkaian tersebut, jika setelah itu semua hambatan dirangkai seri adalah....

R₁ = R₂ = R = 3 Ω (n = 2)

V = 12 Volt

Rp = R / n

Rp = 3 / 2

Rp = 1,5 Ω

R₃ = 2,5 Ω

Rs = Rp + R₃

Rs = 1,5 + 2,5

Rs = 4 Ω

i = V / Rs

i = 12 / 4

i = 3 A

keadaan II

Rs' = R₁ + R₂ + R₃

Rs' = 3 + 3 + 2,5

Rs' = 8,5 Ω

i' = V / Rs'

i' = 12 / 8,5

i' = 1,411 A

∆i = __ ?

selisih kuat arus

∆i = i - i'

∆i = 3 - 1,411

∆i = 1,588 A ✔
