What is the difference between 120 and 240 volts?
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.
One has a filament designed to work on 120 volts, the other has a filament designed to work on 240 volts.
One has an element designed to work on 120 volts, the other has an element designed to work on 240 volts.
The difference between a 120 volt and a 240 volt is one has more power. Volts are the power that comes from a battery.
About ten volts.
Answer for North American 60 Hertz electrical systems. The voltage between L1 and ground is 120 volts. L2 and ground is 120 volts. Between L1 and L2 is 240 volts.
Both 120 and 240 volts are available in most locations in USA.
What is the resistance of a conductor that carries a current of 120 amperes when the potential difference between its ends is 240 volts?
V/I = R --> R = 2 ohms.
Both. There are three conductors supplying a Canadian residence, two line ('hot') conductors and a neutral conductor. The potential difference between the two line conductors is 240 V, while the potential difference between either line conductor and the neutral conductor is 120 V. Most circuits (receptacles, lighting, etc.) are supplied at 120 V, but 'heavy power' items such as electric stoves, etc., are supplied at 240 V.
On 120 volts it's 1425/120 amps, on 240 volts it's 1425/240 amps.
If your question is "Can 240 be produced from 120 volts"? This would require a step up transformer.
Installation of a distribution service costs and usage of that service costs are the same regardless whether 120 volts or 240 volts are used.
240 volts is a typical single phase voltage (one phase wire and one neutral wire, possibly a ground wire as well) while 208 is a three phase voltage (you will have three phase wires, plus possibly a neutral wire) 208v in a grounded system is actually 120 volts referenced to ground. That is, there are three 120 volt voltages referenced to ground 120 degrees apart. A typical house will have 120 and 240 volts. These… Read More
120 volts and 240 volts. Typically 240 volts is supplied to the house electrical service entrance. It is split into it's 120 volt components via two buss bars. Hooking a circuit up to just one bar yields 120 volts. Hooking into both gives 240 volts.
Yes if you have a step up transformer. Primary voltage 120 volts, secondary output voltage 240 volts.
Voltage coming into the service panel is 240 volts. From the service panel you get 120 volts or 240 volts depending on how you wire it.
These voltages are both wye connection three phase voltages. The voltage difference comes from the primary three phase voltage supplies. 277 volts is obtained from 277 x 1.73 = 480 and 240 volts is obtained from 240 x 1.73 = 415. 480/277 volts is a common three phase American voltage. 415/240 volts is a European voltage. In Canada a common three phase voltage is 347/600. The 240 volts could also be a single phase voltage… Read More
Why are the outputs of AC generators multiples of 120 volts - like 120 volts and 240 volts and 480 volts?
It is simply a product of standardization.
yes, a 240 v circuit normally has 2 120 volt legs which are opposite phases and a neutral wire, there will be 120 volts between either hot wire and the neutral and 240 volts between the two hot wires.
240 watts at 120 volts requires 2 amperes. Power = voltage * current
depending on your country it can be 120 volts to 240 volts
In the unites states there is no difference. But the correct term would be 240 volt. Just as the case of 110 volt really is 120 volt. In older days the 110 & 220 Volt was the actual voltage which powered homes. Now the voltage is 120 & 240 volts and this is not exact. 120 volts will typically be measured at the breaker panel as 116-124 volts and 240 will be around 235-244 volts… Read More
What is the power of an appliance that is operating at a current of 2 amps and a voltage of 120 volts?
Volts * Amps = Watts in this case 120 Volts * 2 Amps = 240 Watts This is true for a pure resistive load. If not the result must be multiplied by a Power factor that is between 0 and 1. 240 watts
Canada and US - Visualize it the other way around. The transformer that feeds your house has a primary of 7200 volts. The secondary voltage is 240 volts. This secondary voltage is a split voltage. There are 3 bushings coming out of the transformer on the secondary side. The two outside bushings have the 240 volts on them. The position of the center bushing splits the 240 in to two 120 volts. This center tap… Read More
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.
In the USA it is usually 120/208 or 120/240 volts In Europe I think it's 220 volts
In North America 120 volts, in the UK and Europe 240 volts.
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.
120 volts for receptacles and 240 volts for large load appliances.
Simply use it. The 240 volt breaker is rated to be able to trip 120 volts with no problem. Of course, pick an appropriate current for the size of the conductors. Naturally, if the 240 volt breaker is double pole, you have a problem, because that is not an expected configuration. Also, don't expect the reverse, i.e. a 120 volt breaker is not rated to trip 240 volts.
Kitchen range which is 220 volts but their is only 110 volt outlets as power throughout the house no 220 outlets.?
your outlets work on AC current(alternating) meaning it cycles from -120 volts to +120 volts 60 times a second.... there are two phases in your house at 180degrees of electrical separation(meaning that while one phase is +120 the other is at -120, +90 -90.. etc etc assuming they are phased properly. so.... from -120 to 0(120 volts of difference in potential) then from 0 to +120(120v diff in potential) you get 240 volts for your… Read More
Yes , with a step down transformer. 240 volts into the primary side H1 and H2 which is stepped down to 120 volts on the secondary side, X1 and X2.
At 120 Volts you would draw about 42 amps. At 240 Volts it would be about 21 amps. For 120 Volts you would need 6 AWG and for 240 Volts you would need 10 AWG.
+Its depends in what country you live. In the Uk its 240 volts, in most of Europe its 220 to 240. In the USA its 120.
Did you buy it in Europe or in North America ? In North America, it's expecting to be powered by 120 volts. In most of the rest of the world, it expects 240 volts. 120 volts, 60 watts: P = E2 / R R = E2 / P = (120)2 / 60 = 240 ohms 240 volts, 60 watts: R = E2 / P = (240)2 / 60 = 960 ohms.
If that is the information that is stated on the nameplate of the device then yes it will operate on 120 volts.
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.
120/240 volts is the working voltage in North America.
On most ranges today a power supply of 120 volts is used. The bulb in the oven is 120 volts. The controls and timers are all operated from 120 volts. The elements on the stove top are usually 240 volts today. Old hotplates used to use a supply of 120 volts.
No. A water heater requires a 240 volt connection and cannot be re-wired to run on 120 volts. There isn't enough amperage in 120 volts to power the heating rods that are inside.
In Europe 240 volts is standard, so no a 115 volt motor will not work. In USA 120 volts is standard, so if your sub-panel has 120 volts, (check with voltage meter) then yes. Read carefully, To get 240 volts in a sub-panel in USA the electric company brings two (2) wires, each wire has 120 volts, 120 + 120 = 240. One of those 120 volts will run your motor. Look for the wires… Read More
240 watts to 120 volts? Or 240v to 120v? What kind of meter? As in an electrical test meter?
In the USA houses would have 120/240 volts. 120 volts at most receptacles and lights and 240 volts for larger equipment like your stove, dryer, hot water heater.
Remember Watts = Amps x Volts. With your 2500 watt generator you can load it up to, I = Watts/Volts, 2500/120 = 21 amps at 120 volts or 2500/240 = 10.4 amps at 240 volts if your generator has a 240 volt output. To determine want can be run, check the amperages of your devices you want to plug in.
If it says 120/240 or 120-240 VAC or something similar then the indication is that it can operate at either voltage. There maybe a requirement to install or remove jumpers or a rewiring may be required. Check the manual.
Watts = Amps x Volts. Amps = Watts/Volts. 10000/120 = 83.3 amps can be used at 120 volts. On a generator that large it is most likely that it also has the capacity to produce 240 volts. 10000/240 = 41.6 amps can be used at 240 volts. What you can connect to the generator will be totals of the amperage of devices that do not go above these amp ratings.
Yes. It is 60 Hz between 110 and 120 volts on each of two bus bars with 220 to 240 volts between two bus bars.
No. The same watts are consumed with either voltage. The advantage of 240 is the smaller wire size required to carry the load. And 240 volts can be life threatening.
In the US a house would be supplied with 120/240 volts from a transformer. Two ungrounded conductors (hot wires), one from each end of a winding in the transformer and a grounded conductor (neutral wire) that comes from the middle of the same winding. There is 240 volts between the two hot wires and 120 volts from each hot to the grounded conductor. A single pole breaker would supply 120 volts (attaches to one of… Read More
If you mean that the lamp is rated for 240 volts then yes, a 120 volt bulb will operate in it if the lamp bases fit. If the 240 volt lamp is operating on 240 volts then no, a 120 volt lamp will not work in the fixture.
Yes, it will give you only 1/4 of of its rating
