Three phase power is almost never supplied to a residence. Power is supplied in two 240-volt lines, referenced to ground, which is also typically wired, giving you three overhead (or underground) lines for supply to a typical residence. A larger apartment building might use three-phase power.
AnswerSome countries do indeed supply residences with three-phase supplies instead of single phase. For example, the recently-constructed, two-bedroom, villa in which I live here is Cyprus has a three-phase service and this can be confirmed by examining the three-phase energy meter and the three-phase distribution panel. I don't really know why this should be the case, other than for the purpose of load sharing, as the villa's load is typical of residences elsewhere.
The national electrical grid.
That happens when the appliance supplied by the outlet is switched off.
Mainly because your home is supplied with a.c. not d.c. Even those appliances (audio systems, etc.) that require d.c. supplies can be connected to an a.c. supply, because they have internal transformers/rectifiers which change the a.c. voltage to the required d.c. voltage.
in parallel circuit voltage remains same ..... so all the appliances run at their rated voltages without having any problem as real power supplied depends on voltage .... p=(v^2)/R
Someone else may be able to give some more specific information about regional variations in Nigeria. For more general information please see the Related Question shown below and please look for Nigeria in its Related Links.
North America uses 120V and I believe European countries run on 220V
The average household in the United States is supplied with around 120 volts of electricity.
"Household" water is also referred to as "Tap" or "Reticulated" water. It is the water that is normally supplied to the house for general use.
The national electrical grid.
That happens when the appliance supplied by the outlet is switched off.
The distribution of blood in the capillaries is regulated by the smooth muscles contracting or relaxing. This occurs due to the needs of the cells supplied by the capillary.
When doing voltage drop calculations the voltage to the connected devices should not drop below 3 % of the supplied voltage. <<>> "Most" appliances? that a tough one there is no standard. A few percent is no trouble, different appliances have different tolerances: no generalizations are possible.
Yes you can. Most electrical appliances will work if supplied with power that's within 10% of their voltage rating.
An electrical distribution centre is used to distribute circuits through out the building that it supplies. An electrical panel in your home is classified as an electrical distribution panel. The electrical distribution panels come in varying sizes and voltage ratings depending on what the building requirements are. Amperages for different loads are supplied through breakers that are part of the distribution panel.
Yes, the Ohio Revised Code section 5321.04 states under Landlord Obligations: (4) Maintain in good and safe working order and condition all electrical, plumbing, sanitary, heating, ventilating, and air conditioning fixtures and appliances, and elevators, supplied or required to be supplied by the landlord;Necessary appliances are defined as a stove, refrigerator, furnace, and air conditioning unit.
It isn't an accident. Each country has to select a working voltage for all its electrical appliances. When everything works on a standard voltage it simplifies the market for appliances. In your country it's 220 v, in Europe it's 230 v and in the US it's 120 v, or 240 v for high-power appliances.
Using a distribution system (e.g. 11 kV in the UK) as an example, the primary of a three-phase distribution transformer is delta-connected, which requires to be supplied by three line conductors. So a neutral conductor is superfluous.
