You have to go right back to the source and find out how the electricity is produced. Coal fired, hydro, natural gas turbine. There is a specific cost for each method. For transmission of electricity over hundereds of miles the higher the voltage (250,000 and 500,000 volts) the better the cost savings. When the voltage gets to your house 120 or 240 volts does not matter. You are charged by the amount of watts that you use. Watts = amps x volts. What you pay per Killowatt/hour (1000 watts per hour) is the accumulated costs of everything it takes to get the power to your house.

600 watts requires how many amps?
It depends on the voltage source. watts = voltage * voltage / resistance and amps = voltage / resistance example 1: To produce 600W from a 120V source, you need a resistor of size 120V*120V/600W = 24 Ohm. This would pull 120V/24 Ohm = 5 amps. example 2: To produce 600W from a 240V source, you need a resistor of size 240V*240V/600W = 96 Ohm. This would pull 240V/96 Ohm = 2.5 amps.
Can 240V washer run on 120V outlet?
No.
Can you run your neon sign of 120v 50hz 60hz 0.6a 7.5kv 30mA in an Australian 240v power outlet?
No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V
You are building a new house and trying to decide between 120v and 240v which is better More practical?
In the US, both 120v and 240v will be needed for your home, as different appliances need different voltages. Your TV needs 120V, while your electric dryer and stove will need a 120V/240V supply. If you have an electric water heater, or central AC unit, they will need a 240V supply.
Why are you not getting 240v between the two hot wires?
Because they are "in-phase". In order to get 240v, you need two 120v Alternating Current lines that are 180° out of phase, that is, opposite phases. Only when one line is +120v and the other -120v will you see 240v between the wires.
If you put a 60W 120V bulb in a 120V lamp that has a transformer for 240V and plug it into a 240V outlet will it work or blow the circuitry?
Off hand no but your explanations are not clear as to who is doing what to whom,,
Can I use 120v 10a 1250 w cable for projector 110-240v power in India?
You can use 120v 10a 125w cable projectors 110-240v power in India.
You have 120v photo flash lights - how do you use them with 240v in Oz?
Power adaptors are readily available that plug into Australia's 240v outlets, converting to 120v. Find them in travel, luggage and electronics stores.
How many amps in 180 watts?
It depends on exactly what you are talking about.Something that is described as "X" watts is really just a resistor of a fixed size that, when connected to the proper voltage supply, will produce "X" watts of energy (light, heat, sound, etc.)So, if you have something that is declared as 1800W and is supposed to be connected to 120V, then you have a resistor that is of size:120V*120V/1800W = 8 OhmWhen plugged into the proper 120V source, you will pull120V/8Ohm = 15 AmpsIf you have something that is declared as 1800W but is supposed to be connected to a 240V supply, then you have a resistor that is of size:240V*240V/1800W = 32 OhmWhen plugged into the proper 240V source, you will pull240V/32Ohm = 7.5 AmpsSo, even though both of these things were called "1800W", the key factor is what voltage they are supposed to be driven by in order to get that 1800W. These items are not interchangeable.The 32 Ohm device will not produce 1800W on a 120V source. It will produce only 450W and pull only 3.75 Amps.The 8 Ohm device will not produce 1800W on a 240V source. It will produce 7200W and will pull 30 Amps.
