To convert 220V to watts, you need to know the **current (in amperes)** or the **power factor** of the device you're considering, because power (in watts) is calculated using the formula:
\[
\text{Power (W)} = \text{Voltage (V)} \times \text{Current (A)} \times \text{Power Factor}
\]
- **Voltage (V)** is 220V in your case.
- **Current (A)** is the amount of electric current the device uses.
- **Power Factor** is a number between 0 and 1 (for AC systems), which tells you how much of the electrical power is being used effectively. For simplicity, assume a power factor of 1 if the device is purely resistive (like a heater or incandescent bulb).
So, if you have a device that uses 1 amp of current and has a power factor of 1, the power is:
\[
\text{Power} = 220V \times 1A = 220 \, \text{watts}
\]
If the current is higher, the wattage increases proportionally. For example, if the current is 5 amps, the power would be:
\[
\text{Power} = 220V \times 5A = 1100 \, \text{watts}
\]
In summary, **220V** alone doesn't directly tell you the watts—it depends on the current drawn by the device.
\[
\text{Power (W)} = \text{Voltage (V)} \times \text{Current (A)} \times \text{Power Factor}
