###### Current Electricity – Solutions

**1) The storage battery of a car an emf of 12 V. if the internal resistance of the battery is 0.4Ω, what is the maximum current that can be drawn from the battery?**

Solution:

According to the question it is given that:

E = 12 volt, r = 0.4 Ω

As, I = E/R + r

Where, E = electromotive force of the cell

And r = internal resistance of the cell

R = external resistance

I = current flowing in circuit

For maximum current, R= 0
