A watt (W) is a unit of power, representing the rate at which energy is used or produced. So, when you say "10 watts," it means 10 units of power are being used, transferred, or generated.
To give you a few examples:
- **Light Bulb**: A 10-watt LED light bulb uses 10 watts of power to operate. It's relatively energy-efficient compared to older incandescent bulbs, which could use 60 watts or more for similar brightness.
- **Electrical Appliances**: A small electronic device like a phone charger or a fan might use around 10 watts while running.
It’s just a measure of how much electrical energy is being consumed or produced every second. In simple terms: the higher the number of watts, the more power a device uses or produces.
