240V is much more effecient, and you can put more heaters on a 20 amp circuit than you can a 120V.
Electric stoves require 240 V typically. A gas stove may only require 120 V.
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
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.
120v /240v
Absoluteyl not.
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.
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.

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.
No, unless it's a gas range. An electric range requires 240V and 40A while a small appliance will be 120V and Max 15A.
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.
Power adaptors are readily available that plug into Australia's 240v outlets, converting to 120v. Find them in travel, luggage and electronics stores.
120v and 240v
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.

You will burn up your appliance!!!!!
