Since the equation for watts is:
Volts * Amps = Watts
that would mean
12 Volts * 1 Amp = 12 Watts
If you can find the wattage of the fan and you know the voltage of the fan use the following equation. Amps = watts/volts.
There are two temperature categories for copper buss bar. For a 30 degree C rise the sizes are 1/4" X 1" or 3/8" X 3/4". For a 50 degree C rise the size is 1/4" X 3/4". Both of these temperature categories will handle 400 amps.
No, 12 volt AC is a different from 12 volt DC. Have a second look at the 12 AC volt adapter's output label. Most adapters contain a bridge rectifier in them that makes a conversion within the adapter. An example of this is in phone chargers.
In most cases that will work just fine. But it might not; you just have to try. Going smaller is safe.
You don't! They are two different entities - like converting cars to washing machines!
Simply put:
Voltage is equal to resistance multiplied by current
therefore current = voltage divided by resistance
therefore a resistance of 23ohms at 230 volts will draw 10amps current.
Watts is equal voltage multiplied by current
therefore a 230volt fire drawing 10 amps equals 2.3kilowatts or 2300 watts.
Use this for one hour and your electricity usage equals 2.3Kilowatt hours, say costing approx 15p per KWH = 34.5 pence.

It's the standard Type 'G' 3-pin plug used in the UK for electrical equipment and appliances. It should always contain a cartridge fuse of the right size to match the current or "amperage" drawn by the equipment/appliance it is supplying with power. Standard fuses to fit the plug are available in 13 amp, 5 amp, 3 amp and 1 amp sizes. For more information see the Related Link and the answer to the Related Question shown below.
A motor-generator or a solid state power converter can do this.
I believe it would be best for you to ask your local Electric Company..considering that different areas may have different hours? Hope tis helps..:)
In North America, it is 60 Hertz, and in Europe it is 50 hertz.
General Electric makes and sells refrigerators that use 220 volt electricity. They are manufactured for use overseas, but are sold in the US as well.
Power circuit carries high power and costly devices. If there is some unwanted power signal(noise) in the wire it can damage the device. To reduce this effect earth is necessary.
Lighting circuit carries low power(current).So, we ignore the earth terminal.
Answer for UK
Lighting cables do normally include a protective (earth) conductor, and this is terminated in each ceiling rose, as are the line and neutral conductors. Whether or not the earth terminal is actually then used depends on the luminaire (light fitting). For example, if it is simply a suspended lamp then the earth connection is not used; on the other hand, if it is a fluorescent lamp enclosed in a metal enclosure, then the enclosure is connected to the earth terminal.
US homes use a 240 volt single phase 'Edison' system. It is a 3-wire (4 with the ground) system. Phase to phase measures 240v, while each phase to neutral measures 120v.
In the US the larger prong is Nuetral and the smaller is Live or Positive.
One HP is equal to 746 watts. Therefore 2.5 HP equals 2.5 x 746 = 1865 watts.
Electrical plugs in the UK have 3 prongs, similarly to the US. A Hot, a Neutral and a Ground (earth).
The Ground prong, if present, is a bit longer than the others so it makes contact first when inserted into a socket. The other two prongs are partially insulated near the base of the plug. These are both safety features. As the longer ground pin makes contact first, it is less likely to fault. The partially insulated pins make it less likely someone might touch a conductive surface when inserting or removing a plug.
A longer answer
The UK and Republic of Ireland use a power outlet plug and socket system which is totally different to the rest of Europe:
It is a very good plug and socket system but not many other countries have adopted it - probably because they didn't invent it!
The Related Link shown below and the answer to the Related Question also shown below are relevant to this question.
m means milli,
as in 1/1000
A means Amps
50mA is =
0.050 Amps
Amps is the amount of current passing through a device.
36.6 amps maximum at 120 volts, but should not be loaded to over 29 amps. At 240 volts it will produce a maximum of 18.3 amps but never loaded to any more than 14.6 amps.
It may or may not work. The timer & clock for sure will not be accurate.
No.
It'll overload and fail just about immediately.
It's possible - but not recommended - to run two 110 v heaters in series from a 220v circuit.
Current carrying capacity is different for aluminum from that of copper cable. Under different conditions like, type of insulation, number of conductors, in conduit, underground, in air, single or multilayer, system voltage, the current carrying capacity varies a bit. Hence You must refer a standard chart from a reputed cable company.
