Question 2.4: An electric hair dryer has a power rating of 1000 W. How muc......

The quantity to be found is amperage, or current. The known quantities are power and voltage. To solve this problem, choose the formula shown in Figure 2–22.

I=\frac{P}{E}

\mathrm{I}=\frac{1000 \mathrm{~W}}{120 \mathrm{~V}}

\mathrm{I}=8.333 \mathrm{~A}
