Answer with Explanation:
We are given that
Current,I=12 A
V=11.5 V
I'=9 A
Internal resistance,r=0.05 ohm
a.We have to find the emf of battery.
![E=V+Ir](https://tex.z-dn.net/?f=E%3DV%2BIr)
Using the formula
![E=11.5+12(0.05)=12.1 V](https://tex.z-dn.net/?f=E%3D11.5%2B12%280.05%29%3D12.1%20V)
b.Voltage of ligh
![V'=I'R_{light}=9\times \frac{11.5}{12}=8.6 V](https://tex.z-dn.net/?f=V%27%3DI%27R_%7Blight%7D%3D9%5Ctimes%20%5Cfrac%7B11.5%7D%7B12%7D%3D8.6%20V)
![I_{motor}=\frac{E-V'}{r}-9=\frac{12.1-8.6}{0.05}-9=61 A](https://tex.z-dn.net/?f=I_%7Bmotor%7D%3D%5Cfrac%7BE-V%27%7D%7Br%7D-9%3D%5Cfrac%7B12.1-8.6%7D%7B0.05%7D-9%3D61%20A)
Hence, the current through the starting motor when the light areon=61 A
Ok this is hard but I think the answer is 34
