Question

the storage batery of car has an emf 12v .if the internal resistance of the battery is 0.4 what is the maximum current that can be drawn from the battery

Answer 1

Hey mate !!!


here is your answer!!!


EMF => 12 V

internal resistance => 0.4 ohm


now , maximum current drawn. from battery =>


V = I R


12V = 0.4 x I

hence , current is => 30 Amperes



hope it helps you dear!!!

thanks

Answer 2

Emf= 12v (v)
Internal resistance = 0.4ohm
So according to formula ;
V = ir
i = v/r;
i = 12/0.4;
I = 30 Amp..
And that is your answer..

Hope it is correct and helped..
