Why is it electrical power is normally transmitted at high voltage?

Simplistically Power is Voltage times Current. Sending at domestic voltage requires much more current to be sent for the same power and therefore much thicker wires, heavier equipment and more repeater Transformers as over distance the resistance of the wires and switches would cause the voltage to fall quickly below domestic. For the same power delivery, sending at higher voltages requires less current, lighter wires, and voltage losses over distance are more easily managed so much less equipment is required.

Difference between watt and volt-amperes?
Although we can't necessarily see electricity, we can measure it by its effects. An ampere, or amp, represents the amount of current in a circuit. Voltage is defined scientifically as the circuit's "potential difference," and can be seen as the amount of "pressure" that drives electricity in a circuit. Watts are a measure of the use of electrical power, and one watt is equal to one volt multiplied by one amp.Additional AnswerThe watt is used to measure an AC circuit's true power, whereas a volt ampere is used to measure the circuit's apparent power.Apparent power is the product of current and voltage, whereas true power is the product of current, voltage, and power factor.The true power of an AC circuit is measured using a wattmeter, whereas the apparent power is the product of current and voltage.
How do you improve torque and power transmitted without slipping using the uniform pressure theory and uniform wear theory?
the torque transmitting capacity according to uniform pressure theory is more than the uniform wear theory. but if you want to improve the torque transmitting capacity you have to increase the following parameters 1)coefficient of friction 2)number of friction and pressure plates 3)dimensions of the plates
What is a number to the 0th power?
a number to the power of 0 is one. Observe below: 10 to the power 5 = 100000 10 to the power 4= 10000 10 to the power 3 = 1000 10 to the power 2= 100 10 to the power 1 = 10 10 to the power 0 = 1 ______________ Same conclusion, different view: Any real number (other than zero) to the 0th power equals 1 (one). This is related to the subtraction of exponents being equivalent to division. 10 to the 7th power divided by 10 to the 4th power equals 10 to the 3rd power; you subtract exponents. 10 to the 7th power divided by 10 to the 7th power would of course equal 1, and if you subtract exponents you would have 10 to the 0th power.
Dual power supply?
Dual power supply is used to describe a computer system with two power supply units (PSU's). This is to provide extra power for the computer's internal components.
The type of theory of power that argues that many people have access to power is a?
pluralist
How electrical power is transmitted from power plan to the consumer?
electrical power from the power plant to consumer goes through the transmission & distribution system, first we transmit the high voltage power from the power plant to sub station in sub station we step down the voltage according to need & distribute it to the demand.
What is the best form of energy?
Electrical Heat Light Sound Mechanical Kinetic
What happens to the electrical energy when power is transmitted through long distances?
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.
Will the power consumed by an electrical appliance increase with a reduction of applied voltage?
Power consumed by an electrical appliance will increase with a reduction of applied voltage.
What is the pushing power of an electrical source?
voltage
What is the electrical voltage are supplied by the power supply on your system?
The electric voltage are energy to my system.
What is electrical pressure?
Electro motive force = EMF = Voltage.
What does an electrical circuit need to provide the power?
An electrical circuit needs Voltage-electrical pressure pushing electrons, and Amprege-electron flow through a conductor. P=IxE (Power= Voltage x Amprege.
