How much power is used by a washing machine if it does 7,200 joules of work in 3 minutes?

So, the power that used by the washing machine is 400 Watt.

Introduction

Hi ! Here, I will help you to calculate the power generated. Power is work done per unit time. If a person or machine can do a large amount of work in the shortest possible time, it will produce or require a large amount of power. The relationship between power, work, and time is expressed in the equation:

[tex] \boxed{\sf{\bold{P = \frac{W}{t}}}} [/tex]

With the following condition :

  • P = power that produce or require (Watt)
  • W = work that had done (J)
  • t = interval of the time (s)

Problem Solving

We know that :

  • W = work that had done = 7,200 J
  • t = interval of the time = 3 minutes = 3 × 60 = 180 s

What was asked :

  • P = power that used = ... Watt

Step by step :

[tex] \sf{P = \frac{W}{t}} [/tex]

[tex] \sf{P = \frac{7,200}{18}} [/tex]

[tex] \boxed{\sf{P = 400 \: Watt}} [/tex]

Conclusion :

So, the power that used by the washing machine is 400 Watt.
