Question

The storage battery of a car has an emf of 12 v if the internal resistance of the battery is 0.4ohms What is the maximum current that can be drawn from the battery​

Answer 1

V=IR

12=I×0.4

12×10/4=I

30A=I

Answer 2

Answer:

Answer: E = 12v

Internal resistance r = 0.4 ohm Now maximum current that can be drawn from the battery = I

Now applying ohms law E = Ir

I =E/r = 12/0.4 = 30A
