What is the internal resistance of an automobile battery that has an emf of 12.0 v and a terminal voltage of 18.4 v while a current of 7.20 a is charging it?

0.888 ohm

Explanation:

We have given that the battery has an emf of 12 volt that E =12 volt

Terminal voltage V =18.4 volt

Current through the battery is =7.20 A

We have top find the internal resistance of the battery

Now according to Kirchhoff's law V=E+IR

So

So the value of internal resistance of battery is 0.888 ohm

the body's situation won't change the forces are equal opposit and on the same body
