After long use of car, as given in question 33, the internal resistance of the storage battery increases to `500 Omega`. What maximum current can be drawn from the battery ? Assume the emf of the battery to remain unchanged.
Text Solution
Verified by Experts
The maximum current can be drawn from a battery by short circuiting it. Then V = 0 and `I_(max)=epsilon//r =12//500=2.4xx10^(-2)A= 24 mA` Now, the battery must be recharged before use.
