How many volts is 500 watts?
The question is invalid. Volts is a unit of electrical potential in fundamental units of joules per coulomb. Watts is a unit of (electrical) power in fundamental units of joules per second. As such, you can not determine volts from watts without knowing something else, such as amperes (coulombs per second) or ohms. The conversion of Amps to Watts is governed by the equation Watts = Amps x Volts. For example 1 amp * 110 volts = 110 watts You have two unknowns for this equation, 1) the voltage which you want to find, and 2) the amperage. You must know the amperage to find your answer. In household current the voltage is 110-120. However, if you use a car battery, the voltage is 12. You could have the amperage and then use the equation above. 4 amps: 500watts = 4amps X ? volts. 500 watts/4amps = 125volts (close to household current) 42 amps: 500watts = 42amps X ?? volts. 500watts/42amps = 11.9volts prox. (close to a car battery) 1 amp: 500watts = 1amp X ??? volts. 500watts/1amp = 500volts (about like a large electric eel--300 to 800 volts)
What is kilowatt hour use of roof deicers?
A kilowatt hour is the use of 1000 watts of power in 1 hour. The deicers should have a rating of a voltage such as 110 volts or 220 volts and a current of "X" amps. Multiply the voltage (in volts) times the current (in amps) and you will then know how much "power" in watts the deicer uses. My guess is you will see numbers such as 120 volts at 5 amps. Therefore 120 x 5 = 600 watts per hour or .6 kilowatts per hour.
If an appliance draws 10 amps and the line voltage is 110 volts the power consumption is?
Power = volts times amps, so an appliance drawing 10 amps at a line voltage of 110 volts is consuming 1,100 watts. Keep in mind, however, that in a non purely resistive load, the phase angle of amps to volts might not be zero degrees, so the calculation becomes more complex, and depends on power factor, or phase angle.
How will a 3 phase panel give you 110 volts and 220 volts?
A three phase panel will not give you 110 and 220 volts. A three phase four wire panel will, but not at these voltages. The nearest voltages will be 120 and 208 volts. The 120 volt is the wye voltage of 208 volts. 208/1.73 = 120 volts. A single phase three wire panel will give you 110 and 220 volts.
How much power is a hair dryer using if it operates at a voltage of 110 volts and has a current of 6 amps?
About 660 watts. A hair dryer has a small blower motor and a resistance winding that heats up. The formula is watts = volts x amps x power factor. In the case of a resistive load like the wire that heats up the PF = 1. However, the blower will have a lower PF of about .8.
