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. A 75-watt, 120-volt light uses $$\begin{aligned}
f = \frac { P N } { 60 } \quad \text { where } & f = \text { frequency in hertz } \
P & = \text { number of pairs of poles } \
N & = \text { revolution per minute }
\end{aligned}$$ ampere. How many amperes are used by the 5 lights connected in parallel?
