How much current does a 1500W electric appliance draw in a 120V circuit?

Click For Summary
SUMMARY

The current drawn by a 1500W electric appliance in a 120V circuit is calculated using the formula P = VI, leading to I = P/V. Substituting the values, I = 1500W/120V results in a current draw of 12.5A. This calculation is straightforward and confirms that the appliance operates within expected parameters. The power rating indicates the maximum power consumption, which may vary in practical applications.

PREREQUISITES
  • Understanding of electrical power formulas (P = VI)
  • Basic knowledge of voltage and current relationships
  • Familiarity with units of measurement (Watts, Volts, Amperes)
  • Concept of maximum power ratings for appliances
NEXT STEPS
  • Research the implications of power ratings on appliance efficiency
  • Learn about circuit safety and the importance of amperage ratings
  • Explore the differences between AC and DC circuits
  • Investigate how to calculate power consumption for various appliances
USEFUL FOR

Electrical engineering students, DIY enthusiasts, and anyone interested in understanding appliance power consumption and electrical circuit fundamentals.

Homework Statement


The power rating of an electric appliance is 1500 W. How much current does this appliance draw when it is used in a home electric circuit ( V= 120)?


Homework Equations



P= VI


The Attempt at a Solution



P= VI => I= P/V => I= 1500W/120V = 12.5A

Is this correct? This seems way too simple ha ha ha...so I am not sure.

If this is an early assignment on the topic, you could expect it to be simple. If this is a final assessment assignment you could be forgiven for wondering.
 
It probably is that simple but ...

The power rating is the maximum power that the device can draw. For example the 500W rated power supply in my PC draws a lot less in practice.
 
Thanks for your input CWatters, this is one of the question from my assignment so i can only work with what i have.
