Given,
The resistance of the resistor, R=25 Ω
The current travelling through the resistor, I=8 A
From Ohm's law, the voltage across a resistor is proportional to the current through the resistor.
Thus the voltage across the given resistor is,
[tex]V=IR[/tex]On substituting the known values,
[tex]\begin{gathered} V=8\times25 \\ =200\text{ V} \end{gathered}[/tex]Thus the voltage of the battery of the circuit is 200 V
