Mixed Format $$E _ { L I N E } = \sqrt { E _R ^ { 2 } + E_ X ^ { 2 } }$$

Short Answer

Mixed format: $$E _ { L I N E } = \sqrt { E _R ^ { 2 } + E_ X ^ { 2 } }$$ (with a space between the whole number and the numerator) Fraction format: $1 /4$
Reduce all fractions. An electrician uses $\begin{array}{llcc}k W \text { load }=\frac{\sqrt{3}(E)(I)(P F)}{1,000}& \text {where k W load =3 -phase power in kilowatts }\\ & \text { I= current in amperes }\\ & \text { X= voltage in volts }\\ & \text { P F= power factor }\\\end{array}$
