250w , you divide the 500w value in half as you would be using 1/2 as much voltage.
Voltage x amperage gives you the watts , change one of the factors volts or amps and you change the output of the appliance.

240 heater on 120 volts
The load is a resistive load and as such it is governed by Ohm's law. Current is directly proportional to the voltage and inversely proportional to the resistance. As the voltage goes down so does the current. We will take a 500 watt heater at 240 volts = 2.08 amps. R = E/I = 240/2.08 = 115 ohms of resistance in the heater. Now take the 500 watt heater and using the same formula and at 120 volts. I = E/R, Amps = Volts / Resistance. 120/115 = 1.04 amps. As you can see ohm's law holds true, the current is inversely proportional to the resistance and as the voltage goes down so does the current. To answer the question, yes a 240 volt heater will run on a 120 volt circuit but at 1/4 of the wattage that the heater is rated at. W = A x V = 1.04 x 120 = 124.8 watts. 500/2200 = .25 or 25%.
So to answer the question a 240 volt 500 watt heater on 120 volts would produce 125 watts output.

the simplest solution is by connecting two 120v 3amps heater in series , the same can be used directly on 240v. However the current drawn will still be 3 amps & Not 1.5 amps. The heater output power will be double that of a single heater running on 120v. ( or equvalent to two heaters operating on 120v. supply ) A more expensive method is to use a stepdown transformer which can be powered on 240v & connect the heater on the transformer 120v side. this method will consume approx. 1.5 amps from the 240v supply.
Electronic technician will convert in no time. You need 240v power transformer in place of same wattage 120V. Super easy.
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
The best voltage for an electric wall heater depends on the specific needs and requirements of your space. Generally, residential electric wall heaters are available in 120V or 240V options. 120V heaters are suitable for smaller rooms or areas, while 240V heaters are better for larger spaces or rooms that require more heating power. It is important to consult with a professional electrician to determine the appropriate voltage for your specific heating needs.
You have to be careful here. A heater will be advertised as "X" watts, but that is only true if you connect it to the voltage source it is supposed to be connected to. If you plug it into a higher or lower voltage source than intended, it will produce a different number of watts.Electric heaters are just resistors. When you run electricity through them, they get hot. If you run more electricity through that resistor, it will produce more heat. If you run less electricity through it, it will produce less heat.As an example, you can find "1500W/120V" water heater elements at the hardware store. This means that if you plug it into a 120V source, it will produce 1500W of heat, and it will pull 1500W/120V = 12.5A of current.You can calculate the resistance of the heater by taking voltage times voltage divided by watts, so this "1500W/120V" heater is really just a resistor of this many Ohms:120V * 120V / 1500W = 9.6 OhmThat Ohm value is physical property of the device. It will not change. If you were to take this heater now and plug it into a 240V supply, you can calculate the amps with voltage divided by resistance:240V / 9.6 Ohm = 25 AmpsAnd, for watts, you can take voltage times voltage divided by ohms:240V * 240V / 9.6 Ohm = 6000WSorry for the long text, but it's crucial that you understand this.If your heater is 1500W and is INTENDED to be running on 240V, you have a 38.4 Ohm resistor. Running that resistor at the lower 208V will produce only 1126W of heat and will pull just 5.4 Amps of current.However, if your heater is 1500W and is indented to be running on 120V, then you have a 9.6 Ohm resistor. You will almost certainly start a fire if you plug it into a 208V supply, because you will be pulling close to 22 Amps and producing 4500W of heat.
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.

as long as the total WATTAGE of the bulbs is the same, you should get the same light and the wires will handle the load just fine.

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.

Assuming it is also rated for 120V., yes. The wattage doesn't change with an increase or decrease in voltage. However, the current draw does. When you double the voltage a load is hooked up to, the Amperage draw (current) drops in half. Example: if a 240 volt heater draws 6 amps, it will draw 12 amps if connected to 120V. If a 120V heater draws 15 amps, it will draw only 7.5 amps when connected to 240V. But power, or wattage stays the same, regardless. And this is what is used to calculate energy usage and therefore, cost. Please note the above answer says "if it is also rated for"
Off hand no but your explanations are not clear as to who is doing what to whom,,
You can use 120v 10a 125w cable projectors 110-240v power in India.
