Chapter 18, Problem 57GP

To determine

The average current drawn by a $1.0hp120V$ motor.

Answer to Problem 57GP

  $6.22A$

Explanation of Solution

Given info:

Power, $1.0hp=746W$

Voltage, $V=120V$

Formula used:

By the definition of the power,

  $P=VI$

Where, $P$ is power, $V$ is voltage and $I$ is current.

Calculation:

Rearrange the expression, $P=VI$ . So, $I=\frac{P}{V}$

Substitute the given values in the expression: $I=\frac{P}{V}$

  $I=\frac{746}{120}=6.22A$

Conclusion: The average current drawn by a $1.0hp120V$ motor is $6.22A$ .
