Given,
The resistance of the circuit, R=100 Ω
The current in the circuit, I = 2 A
From Ohm's law, we have,
![V=IR](https://img.qammunity.org/2023/formulas/physics/college/qyxkyhe6das1rxrn37kfxfu7hnf52d3137.png)
Where V is the voltage.
On substituting the known values,
![V=2*100=200\text{ V}](https://img.qammunity.org/2023/formulas/physics/college/cjnpgl9463i6ot1e34yuswqmozn58tae1z.png)
Thus the voltage of the internal circuit is 200 V.
That is the correct answer is the 1st option.
