Question

How is horsepower relative to the power use of a phone or light bulb?​

Answer 1

More horsepower = more power use.

Step-by-step explanation:

Horsepower is just a measure of power, similar to Watts (1 horsepower = 745.7 W). So, as a simple example, a lightbulb that uses 1 hp will have a higher power use than a lightbulb that uses 2 hp.
