A **watt (W)** is the unit of power in the International System of Units (SI). It measures the rate at which energy is used or produced. In simpler terms, it tells us how much energy is being transferred or converted every second.
### To break it down:
- **Power** is how quickly energy is being used or generated.
- 1 watt is equivalent to **1 joule of energy per second**.
For example:
- If a light bulb is labeled as 60 watts, it means the bulb uses 60 joules of energy every second.
- If a motor is rated at 1000 watts (or 1 kilowatt), it’s using 1000 joules of energy each second.
In electrical terms, you can calculate power (in watts) using this formula:
\[ \text{Power (W)} = \text{Voltage (V)} \times \text{Current (A)} \]
So, if you know the voltage and current in a circuit, you can find out how much power is being used or generated.
