It means that the value of the potential difference supplied between the terminals varies from 240V to 0v and then polarity reverses and voltage again rises upto 240V with time.Then again it falls to 0 and polarity changes back and it rises to 240V. This is one cycle and in India we have a frequency of 50Hz, i.e. it happens 50 times in 1 second
The voltage at any time can be calculated by V=240 sin(wT)
i.e. the voltage at any point is a sine or cosine function of time. w is the angular frequency

Do phones use ac or dc?
Some devices operate on AC and others on DC. Generally, anything that uses mains electricity (120V US, 240V UK) is using AC electricity and things that use batteries or are rechargable like cell phones, ipods, personal CD, use DC electricity.
Full form of PL Lamp?
PL is mean Plug in - Light Bulb, the most comment application is CFL (Compact Fluorescent Lamp) which require assistance components to make it work or light it up, different to incandescent light bulb, it can light up by just itself direct connect to our home electricity ac 100v to ac 240v.
How many amps does a wii use?
Input: 110-240V AC, Output: 12V DC, 3.7A
Is home electricity in the UK ac?
no ! ................
What adapters do you need to plug your 240V Ac plug into a 110V AC supply?
There are no adptors to plug a 240v plug into a 120v receptacle. 240v requires two hot wores and a neutral and ground. 120v requires one hot wire, a neutral and a ground. If you have something that runs on 240/120 you need the cord and adaptor that came with the equipment as you willl need the wires to mate up accordingly.
What types of electricity are used in Australia?
240V AC 50HZ
Is electricity AC Or DC currant which one?
Electricity or rather electric currant can be either AC or DC. AC means alternating current (as in that electricity that is supplied by the mains) and DC means direct current (as in that electricity supplied by a battery)..
How is ac supplied all over the UK?
By electricity pylons and cables
How is ac supplied around the UK?
AC. is supplied through many ways like cables which gets electricity from the generators ( power stations ) i hope this answered your question ox.....

What is a compact fluorescent PI lamp?
PL mean Plug in - Light Bulb, the most comment application is CFL (Compact Fluorescent Lamp) which require assistance components to make it work or light up, different to incandescent light bulb, it can light up by just itself direct connect to our home electricity ac 100v to ac 240v.
What type of load is ac machine?
what machine? example== I have 2 compressors, one uses 240v ac at 3 amps..... the other takes 240v ac at 32amps to put another way, one uses 720watts the other uses 7500watts (7680w)
The purpose of 240V to 12V rectifiers?
The purpose of rectifiers is to change AC to DC.

What is the relation of ac and DC?
DC is direct current, a steady current supplied from a steady voltage. AC is alternating current changing like a sine-wave positive and negative, with the advantage that it can be changed by transformers. DC can be derived from AC by rectification and smoothing circuits, which are built into equipments which draw their power (AC) from public electricity suppliers.
