'Voltage' is electromotive force, and the 'Watt' is a unit of power.
You can plug a 240 watt appliance (light, toy, radio etc) into a 120 volt socket as long as the appliance is rated for 120 volt AC operation.

How many watts is light bulb 120 VAC 60Hz 300mA?
Multiply the current by the voltage: 120 times 0.3, which is 40 watts.
How 240 VAC achieved in a 120 VAC environment North America home?
By connecting two separate 120 VAC legs into one. If they are and if it comes to your home from a local utility they will be, it will add to 240. Whenever combining AC or Sine waves into one for the purpose of adding they must be in phase.
How many watts does a CFL bulb use?
The answer to this is country-specific. In the United States: Residential 120 VAC. Commercial also uses 277 VAC Elsewhere in the world: 220 volts to 260 volts, most frequently 230-240 volts AC.
When you say an outlet 220v 30a what does it means?
This is a special purpose outlet, likely for a dryer. Normally in a house electric panel you have 120 VAC as the normal and 220 or 240 as a higher voltage. The 30 A is for 30 Amps. You can only plug in an appliance that has those ratings. You can't plug in a 120 V device.
Can you convert a 120 volt plug in into a plug to go in your cigar plug in a car?
You could if you have an inverter that can change 12 VDC to 120 VAC. Just plug it into the cigar lighter socket. On the back of the inverter there will be a 120 volt receptacle built into the inverter. Check the load of what you want to plug into it to ascertain that you purchase the correct size of inverter. <><><><><> Keep in mind that power is power, and a typical cigar lighter socket puts out about 72 watts. The inverter will only be able to do less than that.

266 KW how many amps?
Watts = current x volts for a resistive load. You need to know a voltage to calculate amps. If it is a 120 VAC residential voltage it would be a whopping 266,000/120 = A or 2,216.7 Amps. If it is 240 VAC then half that. To put that in perspective the service to a typical residence might be between 100 and 200 Amps.
What is the voltage AC recommended for home use?
In the United States, 110-120/240 VAC is the standard.

How many watts and romex gauge is safe for a 15amp breaker?
Assuming 120 VAC in a residence maximum watts = 15 x 120 = 1800 Watts. For a continuous load you can support 1440 watts which is 80& of maximum. You need 14 AWG gauge wire.
How can you find primary from secondary coil?
Primary and secondary are only terms of convenience based on the ratings and purpose of the transformer. If a transformer is labeled 120 to 240 volts, just pick a winding and apply 120 VAC. If the output is 240 volts you found the primary and secondary. If you apply 120 volts and get 60 volts out that means the side where you applied 120 VAC is the secondary.

Can you connect 2 wire to 3 wire house has black white red and ground Appliance has black white and ground?
It seems like you are describing the Red, Black, White and Ground in your electric panel. There is 240 VAC between Black and Red and 120 VAC between Black and White and 120 VAC between Red and White. The electric panel has two busses that supply 120 VAC on alternating breakers in your panel. Essentially, the Red turns into "black" in the panel for all practical purposes. If you have a 240 VAC circuit it essentially takes up to two vertical positions in your electric panel.
In North America what is the normal voltage for a house?
Residential applications are around 110v to 120v, 220-240v, in this range, its 120 volts nominal to a typical wall outlet, however you may read anywhere from 110volts to 120 volts or so, the highest I have seen personally in residential was 245volts.
How many amps does a 2500 watt inverter use?
If we assume that the inverter is used in your car on 12 Volts DC and you are creating 120 VAC; and the 2500 watts refers to the AC side of inverter then for a resistive load Amps = Watts / Volts = 2500/120.
