"40W" refers to a power rating of **40 watts**. Watts (W) are the units used to measure electrical power, which represents the rate at which energy is used or produced. In simple terms, 40W means the device or object is consuming or delivering 40 watts of electrical power.
For example:
- A **40W light bulb** consumes 40 watts of electrical power when it is turned on.
- A **40W speaker** would be capable of producing sound with a power output of 40 watts.
In general, the higher the number of watts, the more energy a device uses or outputs.
