The storage battery of a car has an emf ...

The storage battery of a car has an emf of 12 V. If the inernal resistance of the battery of `0.4 Omega`, What is the maximum current that can be drawn from the battery ?

Text Solution

Verified by Experts

The maximum current can be drawn from the battery when the external resistance of the circuit is zero and is given by: `I= (E )/(r )`
Here, `E=12V`
`r= 0.4 Omega`
`:. I= (12)/(0.4) = 30A`
