50 Hertz Residential Electricity

All of Europe and most of mainland Asia and Africa use 50Hz frequency for their residential electrical needs. Some countries use 50Hz, as they found it economical to maintain and operate power-generating equipment at this frequency.

How much watts in one ampere?

User Avatar

Asked by Wiki User

Since the equation for watts is:

Volts * Amps = Watts

that would mean

12 Volts * 1 Amp = 12 Watts

How much input current is being provided to ceiling fans?

Asked by Wiki User

If you can find the wattage of the fan and you know the voltage of the fan use the following equation. Amps = watts/volts.

How you can find the 4000 amp on bus bar size?

User Avatar

Asked by Wiki User

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.

Can you replace 12v vdc adapter by 12v vac adapter?

User Avatar

Asked by Wiki User

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.

Can you put a 13 amp fuse in a 10amp plug?

In most cases that will work just fine. But it might not; you just have to try. Going smaller is safe.

How do you calculate kilowatt to watt?

User Avatar

Asked by Wiki User

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.

What is 13 amp plug?

User Avatar

Asked by Wiki User

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.

Is there anyway to get 120V 60hz from a 100V 50hz power supply?

User Avatar

Asked by Wiki User

A motor-generator or a solid state power converter can do this.

  1. Motor-generators are an old electromechanical technology. In this case you would use a 240V 50Hz synchronous motor and a 110V 60Hz generator with their shafts connected so the motor turns the generator.
  2. Solid state power converters use a high power rectifier to convert the input AC to DC, a precisely tuned oscillator to set the output frequency, and a high power class AB push-pull amplifier powered by the high voltage DC and driven by the oscillator to generate the output voltage.

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.

Why it is necessary to have an earth wire installed in a power circuit but not in a lighting circuit?

User Avatar

Asked by Wiki User

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.

What are the averag volts used in a US Home?

Asked by Wiki User

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.

How many watts for 2.5 amps?

User Avatar

Asked by Wiki User

One HP is equal to 746 watts. Therefore 2.5 HP equals 2.5 x 746 = 1865 watts.

How many prongs does a standard electrical plug have in the UK?

User Avatar

Asked by Wiki User

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:

  • All power socket outlets are rated at 13 amps to take a standard 13 amp plug.
  • Each power socket has a protective insulated shutter that safely uncovers the live (or hot) and neutral holes when the plug of an appliance is inserted. The shutter immediately covers the holes over again when the plug is removed. The shutter is operated by the insertion of the earth (or ground) pin which is longer than the live and neutral pins.
  • Each 13 amp plug has 3 rectangular (not round) pins: a live, a neutral and an earth pin. There is also a fuse that should be selected to be of the right size to protect the appliance it is attached-to.
  • The actual plug type is known internationally as Type 'G'.
  • It was designed for use on any normal house mains voltage or frequency and is used in the UK and other countries which have adopted the UK mains power plug and socket system for appliances.

    It is a very good plug and socket system but not many other countries have adopted it - probably because they didn't invent it!

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.

What is the capacity of a 35mm2 cable?

User Avatar

Asked by Wiki User

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.
