Question

the Storage battery of a car has an EMF of 12 volt if intensity resistance of battery is 0.452 what is the maximum current that can be drawn from the battery

Answer 1

Emf of the battery, E = 12 V

Internal resistance of the battery, r = 0.4 Ω

Maximum current drawn from the battery = I

According to Ohm’s law,

E = Ir

I = E / r 

 = 12 / 0.4 

 = 30 A 

The maximum current drawn from the given battery is 30 A.

Next Question

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
