Question 1068731: The formula H=VIE over 746 gives the horsepowerH produced by an electrical motor with voltage V in​ volts, current I in​ amps, and percent efficiencyE in decimal form. What is the horsepower of a​ 240-volt motor pulling 40 amps and having 86​% ​efficiency? Remember to convert percents to decimals in your calculations.
Find the value of W if R= W+ pW,R=​$31.56, and p=20​%=0.2. W=?

he formula H=VIE over 746 gives the horsepowerH produced by an electrical motor with voltage V in​ volts, current I in​ amps, and percent efficiencyE in decimal form.
What is the horsepower of a​ 240-volt motor pulling 40 amps and having 86​% ​efficiency?
Hp = %28%28240%2A40%2A.86%29%29%2F746
Hp = 11.067 horsepower
:
Find the value of W if R= W+ pW,R=​$31.56, and p=20​%=0.2. W=?
W + pW = R
W + .2W = 31.56
1.2W = 31.56
W = 31.56%2F1.2
W = 26.3
