38
39
Multiple Choice
What is the formula to determine the battery capacity (Ah)?
Muatan baterai(Ah) = Kuat arus listrik (A) x lama waktu (h)
Muatan baterai(Ah) = Kuat arus listrik (A) / lama waktu (h)
Muatan baterai(Ah) = Kuat arus listrik (A) + lama waktu (h)
Muatan baterai(Ah) = Kuat arus listrik (A) - lama waktu (h)
