Then as personal appliances began proliferating, they were designed to take advantage of the VAC lighting circuits already used in houses and the concept cemented itself into our culture to where there was no going back. Edison, despite having investing in AEG as Europe began electrifying, was reluctant to allow a system in which Europeans could enter our market by selling electrical products here.
So after also experimenting with different frequencies 40Hz was the first major industrial installation, at the Folsom Power House in California , Edison and Steinmetz settled on 60Hz, partly because of the flicker issue, then also because it would make European equipment incompatible. He wanted it all to himself He wanted DC because he owned the US patent rights to his DC dynamo even though he actually bought his first one, for proof of concept, from Werner von Siemens.
Siemens had not patented it in the US. Only the rich would be able to afford it, and they would all be paying Edison for the privilege. Tesla's egalitarianism ruined his vision. This was extensively covered in The Simpsons :.
Jokes aside, once you pick a value and produce a substantial amount of compatible devices, the price of switching to a different value becomes prohibitively high. We learnt that it was about resources. Europe had abundant iron and was short of copper, hence 50Hz. Whereas mistakenly America and particularly Pennsylvania, had a surplus of copper, hence 60Hz.
Also, lights flicker at twice the AC frequency, one flash on the positive half cycle and one flash on the negative half cycle, not at the supply frequency. In the UK wiring was available nationwide in the late 's. The rest of europe followed shortly after the US. Because it took the UK a bit of time to catch up, they had time to learn an important thing about the previous experience with household electricity - wiring houses was expensive!
They had to use a lot of wire and by doubling the voltage they reduced the current to half thus reducing the wire gauge needed. The AC freq. Up until there was no standard for the mains freq. Westinghouse learned about this becoming a standard but they figured the lights still flicker a bit so they increased the freq.
In the following years they started wiring the entire US and motors and other devices were designed for that freq. Sign up to join this community. The best answers are voted up and rise to the top.

This frequency difference partitions Japan's national grid, so that power can only be moved between the two parts of the grid using frequency converters, or HVDC transmission lines.
Yailen Pleno Pundit. Is v more dangerous than v? Meaning, higher current can be more dangerous than higher voltage; however, since voltage and amperage are directly proportional, v wiring is usually considered safer to work with because it uses fewer volts and as such can only carry half as much current as v wiring.
Enid Ennos Pundit. Can I plug v to v? Very few countries still officially rate their AC mains as V , but DO still call it V and rate their appliances as such. Loren Pflieger Pundit.
Can I use v in v? If we pass current, which is more than the prefferd scaling the cable may melts and leads to explosion. So, from this cables of V can allow V without any damage in the electric cable. Galya Zalama Pundit. Can you run v on v? In answer to the original post: yes, you can use the drill. Everything labeled as v is designed to run from the mains anywhere in europe - be it from our v or mainland europe's v.
Naryis Eslamdoust Teacher. Why does the UK use v? The reason it's V is because that's the power line that has been standardized over here. Some European countries use V , while some specify V ; most appliances will accept V however. Regular appliances like lamps, laptops, and phones do not need access to this power. Vitalij Mainz Supporter. What is the difference between v and v? The big difference between V and V equipment is that the V units draw half the current amps for the same total power consumed.
There is another reason to use V equipment. Because for the same power half the amps are used, motors will run cooler. That helps them to last longer. Caifeng Acuriola Beginner. Does volt need a neutral? The green wire, or bare copper wire, is the ground, which is there for electrical safety. Regular appliances like lamps, laptops, and phones do not need access to this power.
For those who are surprised to hear households have V coming into the home, the way it works is as follows: right prior to the residence entry, the line transformer secondaries are center-trapped so as to provide split-phase V on two hot legs 1 and 2 and neutral at the center tap which is referenced to Earth at the breaker box. For most home outlets, either leg 1 or leg 2 is used with the neutral line to provide V alternating current to power small appliances with a plug-in cord.
For larger appliances, as in the case of the aforementioned oven and laundry machine, they will use leg 1 to leg 2 voltage, which is a straight shot of V line to line out of special outlets, or otherwise specially hardwired to specific areas of the home.
Now, historically speaking, one of the main reasons why the US stuck with V as its standard power supply largely has to do with the fact that it was initially tied to carbon filament lighting. So V was made the standard. The United Kingdom is one area of the world that did change things up after setting up its power grid.
It was much smaller than the United States version, but could not be supported after World War II when the UK began running out copper to rebuild its infrastructure. To fix the problem, it decided to instead build the fuse into their plugs; this, as opposed to having all outlets connected to a fuse box individually.
