Question

Sbuah accu mmpnyai GGL 12V dan hmbtn dlm 0,5 ohm dprgnkan untk mnylakan lmpu dg hmbatan 2,5 ohm..
beda potensial (tgngan jepit) antra ujung2 lmpu adlh

Answer 1

Listrik dinamis
• Rangkaian listrik searah
E = 12 V
r = 0,5 Ω
R = 2,5 Ω
Vj = _?

Kuat arus
i = E / (R + r)
i = 12 / (2,5 + 0,5)
i = 4 A

Tegangan jepit
Vj = i R
Vj = (4) (2,5)
Vj = 10 V ←jwb
