It needs to go to all the homes and increases current i dont know if thats right its just a guess.

Describe domestic electricity distribution?
Generation: Electricity is generated at power plants, which can use various energy sources such as coal, natural gas, nuclear, hydroelectric, wind, or solar power. These power plants produce high-voltage electricity. Step-up Transformer: Before distribution, the electricity is typically passed through a step-up transformer to increase its voltage. Higher voltage transmission reduces energy loss during long-distance transportation. Transmission: The high-voltage electricity is transmitted through a network of high-voltage power lines and substations. These power lines can span long distances, carrying electricity from the power plants to regional distribution centers. Step-down Transformer: At substations located closer to residential and commercial areas, the voltage is reduced through step-down transformers. This process lowers the voltage to a level suitable for distribution to homes and businesses. Distribution Lines: Lower-voltage electricity is then distributed through a network of power lines and transformers at the local level. These distribution lines typically consist of overhead wires or underground cables. Distribution Transformers: Near or within residential and commercial areas, distribution transformers further reduce the voltage to levels suitable for household use, typically 120/240 volts in North America or 230 volts in many other parts of the world. Service Lines: From the distribution transformers, electricity is sent through service lines to individual homes and businesses. These service lines connect to the main electrical panel or meter at each building.
What is pre-fault voltage?
It is simply the voltage of the system before the fault occurs.. Most probably this is the voltage of healthy system...
How many 12 kw is in amps?
There are zero kilowatts in amps. A voltage value has to be supplied before an answer can be given. I = W/E. Amps = Watts/Volts = 12000/Volts. Alternatively, you could state the resistance, from which the amps are determined from P/R = I2.
What is the higher voltage at the electrode before the arc is struck called what is it's advantages to welding?
Open circuit voltage is the voltage at the electrode before striking an arc (with no current being drawn). The higher the open circuit voltage, the easier it is to strike an arc because of the initial higher voltage pressure.
Does voltage split equally in parallel?
The voltage going into each parallel node will be equal to the voltage of the node before it, as long as the resistance is the same. For example, if you have a current of 5 volts split between two 1k ohm resistors, each 1k ohm will have 5 volts before the resistor drops the voltage.
Why is alternating current used for domestic purposes?
Alternating current is easier to distribute than direct current, because alternating current can be raised or lowered in voltage by a transformer. This allows very high voltages to be used in long distance transfer of electricity, which is then stepped down several times before being supplied to the end user. As the voltage is increased in a circuit, the current, as measured in amperes, decreases for a given load. This allows the use of lighter wire to transmit large amounts of electricity.
What is the voltage that can be generated by 1square mm copper wire?
A copper wire by itself won't generate any electricity at all. You'll need to have a length or a loop of it moving through/surronded by a magnetic field before you can get a voltage out of it.
Does the power supplied to trip shunt trip breaker have to be applied momentarily or can it latch?
A shunt-trip breaker trips when voltage is applied to the coil. It does not self-reset when the voltage is removed, the breaker must be reset manually. The trip voltage can either latch or be applied momentarily, but must be de-energized before the breaker will reset.
Give some safety measures when dealing with electricity?
There are many safety measures when dealing with electricity. The highest priority is to remove the voltage potential from the circuit before working on it. Doing this one thing will save you from a shock that could have the potential to kill you.
How many leopards were there in Africa before they decreased?
More than there were prior to when they decreased. At least seventeen.
Does the alternating current supplied to the armature winding of a DC motor gets converted to dc by a commutator before it flows through the armature coil of the DC motor?
The commutator is a rotating switch, which reverse the polarity of the generated voltage every half-cycle. So it acts to rectify the output voltage.
How do you wire a multi tap ballast?
It depends on what voltage you're connecting it to. If this is for a light fixture, you need to know what the voltage is that is being supplied to it. On the ballast, it will have different legs that are marked as what voltage they are. Some are 277,208,240,120. Just use the one that corresponds to the supplied power and just leave the rest alone. Hook up the ballast the same way you would any other ballast for that application and you should be fine. Just make sure you shut off the power. Be safe. If you have not done this before, you should seek help from a professional.Good luck
How electricity is transmitted to distant places?
Electricity is transmitted to distant places through wires, held above the ground by pylons. The voltage is increased by transformers, before sending through overhead wires. This is done to reduce the effect of resistance in the wires. By ohms law, the loss of power from the resistance of the lines is less at higher voltage. The voltage is reduced by more transformers locally, before being sent to homes. Locally the powerlines may be buried underground. Alternating current (AC) was adopted as being best for power transmission. One reason is that the voltage of DC cannot be changed using transformers.
Are Grounding electrodes and wires always dead?
Negative, grouning electrodes and wires have the potential of carrying voltage. Always check each wire before touching it as electricity can do strange things.

What was the day of invention of electricity?
Electricity was never "invented" like, say, a toothbrush. Electricity was know to ancients, and its effects were seen by people who had no written language. This was lightning. Much later, static electricity was seen acting on things, and later still, crude voltage cells were constructed using chemicals. The true nature of electricity was considered and investigated by a number of experimenters over a long time before it was understood well enough to explain it.
