An electrical device uses about 27 amps of current from a 240 volt line how much power does it use?

To calculate the power used by the device, you can use the formula: Power (P) = Voltage (V) × Current (I). In this case, P = 240 volts × 27 amps, which equals 6,480 watts, or 6.48 kilowatts. Therefore, the device uses 6,480 watts of power.
