All electric appliances use amps. Amps are a measure of current.
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.
A typical domestic water heater uses 3 kW. On a European 230 v system it would use 13 amps.
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
The formula you are looking for is Amps = kW x 1000/1.73 x E x pf. Use .84 for a power factor value.
yes

The formula you are looking for is I = E/R. Amps = Volts/Resistance.

Need to know the voltage of the motor.
Between 7 cents to 12 cents an hour depending on the wattage and your electric company.
10 amps
i went onto whirlpool's site and checked a basic electric range for some specs.here's a cut and paste from there:Electrical Requirements15 Amps. 60 Hz. 120 V.
Countertop electric roaster ovens are easy to use and can help save on electricity by using a smaller device instead of turning on a standard oven. These roasters can usually be adjusted from a low of 150 degrees to a high of 450 degrees.
In UK voltage, a single oven would use somewhere between, 10-15 amperes and a double oven, 30-40.
