A 25 Ω resistor has 8 A of current traveling through it. What is the voltage of the battery of the circuit?

Sagot :

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
