Quick Scoop

Watts are a unit of power. They tell you how fast energy is being used, produced, or transferred—1 watt = 1 joule per second.

Simple meaning

If something uses more watts, it usually needs more power at that moment.

For example, a 100 W bulb uses more power than a 10 W bulb.

In electricity

In electrical circuits, watts can be found with:

  • W = V × A
  • where V is volts and A is amps.

Quick example

A device that runs at 120 volts and draws 2 amps uses:

  • 120 × 2 = 240 watts.

Why it matters

Watts help you compare appliances, understand electricity use, and estimate power needs for devices.
