AC stands for Alternating Current and DC stands for Direct Current.
no
Like most other countries, you will find that in England we use voltages ranging from almost zero to a few tens of kV, depending on the application. ;) However, assuming you mean the voltage supplied by 3-pin 13A mains sockets (type G) then from 1 January 2004 the mains supply should be 230V (-6%, +10%), 50 Hz (±1%). ie a range of 216.2 - 253V. This replaced the UK's former specification which was 240V ±6% (ie a range of 225.6 - 254.4V). Some "shaver sockets", similar to round 2-pin sockets (type C) found in mainland Europe, will supply 110 V, but be careful since they often have a dual mode 110V/240V.
Some common sources of voltage, (also known as "potential difference" or "electrical pressure") include: For direct current (dc): single dry cells (and batteries containing several cells); dynamos; photovoltaic solar panels. For alternating current (ac): alternators.
For many years, mainland Western Europe has used a mains electricity supply rated at nominally 220VAC @ 50Hz, while the UK used 240VAC @ 50Hz. Currently, ALL Western European supplies are classified 230VAC and most other countries follow this. However the US and Canada use 120 V @ 60 Hz.
You can reduce the voltage fluctuations by first determining what is causing them, then counteracting this cause. In small circuit designs with multiple switching amplifier and ICs, the power or ground lines may become noisy due to this switching. Placing capacitors at the ICs power and ground can reduce this to manageable levels in most cases. Sometimes it can become necessary to isolate specific circuit's power and ground from the system using small inductors as well. If you are designing a power supply, zener diodes, and isolated power outputs (at the same or different voltages) can be used.
In the UK the mains voltage is 240 volts
230 V
Not without a suitable mains adapter to charge the battery. The UK mains voltage is 230 Volts - the US mains runs at just 110 colts.
UK mains electricity operates at a nominal voltage of 230 V (+10%/-6%), at 50 Hz.
No.
It depends what country you're in. Here in the UK, the mains voltage is 230 volts.
Rarely... Electrical companies reduce the voltage to save money on generating power. Most electrical equipment will still operate even if the voltage is within 5% of its rating. For example - in the UK, our mains voltage is rated at 240V, however - the actual voltage supplied is 230V.
it can stop your heart Certainly UK mains voltage,,240 V ac is enough to kill an average person
the voltage of the mains electricity in the UK
It depends on where you live, as most countries have their own standards. In the UK, for example, the nominal (named) mains voltage is 230 V, but it is allowed to vary between +10% and -6%. The nominal frequency of this voltage is 50 Hz, and this is allowed to vary between +/-1%. In North America, the standard nominal supply voltage is 120 V at 60 Hz.
In the UK, the term, 'mains', refers to the supply voltage provided by the distribution system. In most residential properties, the mains' supply is single phase (there are exceptions: some European countries have three-phase supplies), in which case you cannot 'wire' a three-phase load such as an induction motor into the mains.
No. Not unless you use a transformer to change the voltage. In the US mains voltage is 110-120 V and the current 60Hz Alternating Current. In the UK and almost all of Europe mains voltage is 230-240 V and the current 50Hz Alternating Current. So, if you attempt to use a US appliance in the UK the voltage, which is at least twice the amount of that in the US will create double the current in the device. This will either immediately blow an internal fuse, or burn the appliance out. In extreme cases it could even cause a fire.
