The Resistance of a Coil That Uses 800 Watts Is

Short Answer

The resistance of a coil that uses 800 watts is 62 ohms. What is the voltage of the circuit? Round the answer to the nearest hundredth. $$\begin{aligned}f = \frac { P N } { 60 } \quad \text { where } & f = \text { frequency in hertz } \\P & = \text { number of pairs of poles } \\N & = \text { revolution per minute }\end{aligned}$$ $$\text { volts } = \sqrt { \text { watts } \times \text { ohms } }$$
