Look on the back of the equipment for a manufactures label. If the wattage is not on the label just use this equation Watts = Amps x Volts. This will give the wattage that the piano uses whenever it is turned on.
Some where on the electric piano there will be a manufactures label. When you find it the voltage and amperage will be stated. To find the wattage use the formula W = Amps x Volts.
To figure that out you need to know the Amperage that it draws and what the voltage of the circuit is that you're using. Once you know that you can figure out how many watts it uses by doing simple math. Voltage x Amperage = Watts
The electric heater will have power rated in Watts. The Amps it will draw depends on the voltage system you are using. Can be calculated by formula I (Amps) = P / V In the USA with 110V system a 2400W heater will draw 2400 Watts / 110 Volts = 21.8 Amps In Australia with a 230 V system a 2400W heater will draw 2400 Watts / 230 Volts = 10.4 Amps

Hoovers use 1000 - 2000 watts
Some where on the electric piano there will be a manufactures label. When you find it the voltage and amperage will be stated. To find the wattage use the formula W = Amps x Volts.
for a large one it is 4,000 watts and for a smaller one it is 1,000 watts
Electric lights that use from 0.02 watts to 50,000 watts have been manufactured. The CFLs, fluorescent tubes, and incandescent bulbs in your house probably operate in the range of 20-100 watts.
To determine the number of watts of electric energy consumed by electric iron, we need to multiply the volts and the ampere used by that particular electric iron, so the product of those two is the watts used by the electric iron.
An electric piano is played the same way a regular piano is played only you do not have to use as much pressure when hitting the keys. You have more options for creating different sounds with an electric piano.
Volts and watts are different quantities and their relationship also includes the electric current. Voltage times current in amps equals the power in watts use.

I just checked mine in the kitchen. That one uses 1.4 amps at 120 volts, which is 168 watts. Others may be slightly more or less, but that is about average.
