Volts (V) and watts (W) are related through electrical power calculations, but they measure different things:
- **Volts (V)**: This measures the **electric potential difference** or the "pressure" that pushes electric charges through a conductor. It tells you how much energy is available to move the electrons.
- **Watts (W)**: This is a measure of **power**. It tells you how much energy is used or produced over time.
To convert volts to watts, you need to know the **current** (measured in amperes, A). The formula to calculate watts from volts is:
\[
\text{Watts (W)} = \text{Volts (V)} \times \text{Amps (A)}
\]
So, if you know the voltage and the current in a circuit, you can calculate the power (watts).
### Example:
If you have a circuit with **12 volts** and **2 amps**, you can calculate the power:
\[
\text{Power (W)} = 12 \, \text{V} \times 2 \, \text{A} = 24 \, \text{W}
\]
In this case, the power is 24 watts.
So, to convert volts to watts, you always need to know the current (amps) in the circuit.
