To move the energy through the lines to reach the farthest user, electricity leaves the power plant at 24,000 volts to a transformer area, there it is increased to 304,000 volts which is used to move the energy through out the service area and reduced back down to be accepted in your house or place of business
Electricity is transmitted at high voltages to minimize power losses due to the resistance of the wire. Power = Voltage * current, and Voltage = current * resistance. The resistance of the wire does not change with voltage level, so to power losses will be less for the same amount of power as voltage is increased.
AnswerThe answer provided above describes an advantage, rather than the reason, for transmitting energy at high voltages. The primary reason is that, by using high voltages, the resulting lower currents make it possible to use cables with cross-sectional areas that allow the conductors to be light enough to be suspended from towers or poles. In other words, the use of high voltages is what makes energy transmission practical. The advantage of a saving in energy loss, as described above, is simply a bonus!
To reduce power losses.
Power = voltage x current. Higher voltage means less current. Power loss is proportional to the square of the current.
because they feel like it
High voltage.
Electricity for industries are supplied with high voltage.Domestic supply is with low voltage.
The electricity that is delivered to homes from the regional generating stations uses high voltage in its distribution. This is then transformed from the high voltage on the primary side of the transformer to a lower voltage on the secondary side of the transformer. The common household voltage throughout North America is 120/240 volts obtained from the secondary windings of the step down utility owned transformer.
Rubber compound is one of the poorer conductors of electricity. That is why rubber tape is used in both high and low voltage splices.
no...current is a flow of electricity
Electricity is transmitted at a high voltage of 400000 volts so that it may be able to travel for a long distance.
Via a height voltage electrical grid.
Because wires are not perfect conductors, energy is released as heat. This is why electricity is transmitted at very high voltage and low current to reduce energy loss.
The primary reason that power is transmitted at high voltages is to increase efficiency. ... The higher the voltage, the lower the current. The lower the current, the lower the resistance losses in the conductors. And when resistance losses are low, energy losses are low also.
static electricity can be called high voltage static electricity can be called high voltage static electricity can bend water
In electricity? High voltage ,high currents. Low voltage, low currents.
Transformers are used to convert electricity from high voltage to low voltage and from low voltage to high voltage.
Not at high voltage. The Grid Electricity Is divided at subtations to lower voltage for transfer to Houses
Electro motive force = EMF = Voltage.
its because of transformers . they work with pulse
it is an example of current electricity
At a high enough voltage, everything conducts electricity.
