First we need to convert the power from horsepower (hp) into watts. Since [tex]1 hp=736 W[/tex], we have
[tex]P=2.25 hp \cdot 736 W/hp=1655 W[/tex]

Then we know that the electrical power of a device is the product between the voltage and the current:
[tex]P=VI[/tex]
So if we re-arrange this equation, we get the current flowing in the circuit:
[tex]I= \frac{P}{V}= \frac{1655 W}{10.0 V}=165.5 A [/tex]
