To calculate how many amps are drawn by a device using 220 volts, you need to know the power consumption (in watts) of that device. The formula to calculate the current (in amps) is:
\[
I = \frac{P}{V}
\]
Where:
- \( V \) = Voltage (volts)
For example:
If a device uses 2200 watts of power on a 220-volt supply:
\[
I = \frac{2200}{220} = 10 \, \text{amps}
\]
So, a device using 2200 watts on a 220-volt supply would draw 10 amps of current.
If you know the power of the device you're referring to, I can help calculate the exact amps!
