The storage battery of a car has an emf of 12 Volt. If the internal resistance of the battery is 0.4 Ω, what is the maximum current that can be drawn from the battery?
In the given question,
The EMF of the battery is given as
The internal resistance of the battery is given as
The amount of maximum current drawn from the battery is given by =
According to Ohm’s law,
Rearranging, we get
Substituting values in the above equation, we get
Therefore, the maximum current drawn from the given battery is 30 A.
Maximum current drawn from the given battery is 30 A.
