The storage battery of a car has an emf Of 12 v internal resistance of the battery 0.4 om what is the maximum current?
Most Upvoted Answer
The storage battery of a car has an emf Of 12 v internal resistance of...
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.
