voltage is the PUSH on electrons seriously 120 volts is the difference of 240...
Simply said 240 volts is 2 times as strong as 120 volts.
divide 240 by 2 and.. voila.. you get 120!
The differencs is 240 minus 137 equals 103
50% of 240 is 120. 75% of 120 is 90.
240 ÷ 2 = 120
200 percent of 120 is the same as 2 times 120, which is 240.
One has an element designed to work on 120 volts, the other has an element designed to work on 240 volts.
It is simply a product of standardization.
No, it is not possible to use 240 volts with a 120 volt supply directly. You would need a transformer to step up the voltage from 120 volts to 240 volts. Attempting to use 240 volts with a 120 volt supply without a transformer can damage equipment and pose a safety hazard.
Seeing that the question comes from North America the most common duplex receptacle has 110 - 120 volts potential to ground. The second most common potential difference is 220 - 240 volts. These voltages are obtained from a 120/240 volt system common to home connections from the local utility companies.
The maximum voltage rating for a 120/240 VAC breaker is 240 volts.
In the USA it is usually 120/208 or 120/240 volts In Europe I think it's 220 volts
Any where between 220 and 240 volts are a nominal figure in the same voltage range. It is brought about by the power company, as they have a responsibility to keep voltages within a certain 10% range. The load will only notice a difference of 1% on the load current. eg. Wattage load of 2400. Amps = watts/volts. 2400/240V = 10 amps. 2400/220V = 10.9 amps.
If you measure the voltage between the hot wire (480V) and the ground using a meter, the reading should be close to 480 volts. Ground is typically considered to be at 0 volts potential, so the voltage difference between the hot wire and ground should be around 480 volts.
240 watts at 120 volts requires 2 amperes. Power = voltage * current
If that is the information that is stated on the nameplate of the device then yes it will operate on 120 volts.
30 amps.
In North America 120/240 is the main voltages used. It is known as a three wire system. L1 to L2 supplies 240 volts. L1 to N supplies 120 volts and L2 to N supplies 120 volts.
