What is the maximum instantaneous power dissipated by, and maximum current passing through, a 3.0-hp pump connected to a 240-V ac power source?(adsbygoogle = window.adsbygoogle || []).push({});

ANSWER: 6 hp, 13 A

Given:

P = 3 hp = 2238 W (1 hp = 246 W)

V = 240 V

I don't know which formula to use. At first, I attempted to use P = I*V, but, then, I got flustered over the provided formulas in my book. Peak current is mentioned, and there are different variations of P. Did I start off correctly? How am I supposed to execute this problem?

Thanks.
