A1-horsepower, 24-volt dc electric motor that is 80 percent efficient requires 932.5 watts. how much power will a 1-horsepower, 12-volt dc electric motor that is 75 percent efficient require?

A 1 horsepower motor with 75% effiency will require 994. 26 watt

Explanation:

To calculate the effiency, 1 horsepower is equivalent to 745.7 watts

1hp= 745.7 w

So, by using a rule of three the calculation its like this:

745.7  ⇒  100%

X        ⇒  75%

The information about the volts in this example is not required, but it can be used to calculate the current.
