This was due to the results of the War of the Currents between Edison, who supported DC and Tesla for AC power distribution. Although most electronics you find today run off DC power, the transmission of DC power over long distances is not very efficient and requires several substations between the power transmission source and where it is received. AC power after stepped up can be transmission over long distances with little energy loss. The energy loss occurs from heat generated from resistance within the transmission wire.
At the introduction of Edison's system, there was no practical AC motor available. It was primary due to the introduction of the 3 phase AC motor did AC finally win over DC.
Alternating current (AC) is transmitted across large distances at high voltage to minimize power loss due to resistance in the transmission lines. By increasing the voltage, the current flow is reduced for the same amount of power transmitted, which significantly decreases the I²R losses (where I is current and R is resistance). This allows for more efficient long-distance energy transfer and reduces the need for additional infrastructure.
a high power, often class C amplifier.
Cruachan Power Station is a storage hydro-electric power station whereas a Normal Hydroelectric power station is produced and then used, no storage needed.
Alternating current, yes. But it is not quite correct to say "electrons move to the homes... " rather, it is the CURRENT that moves to the home. It is more like a wave, where the energy is transmitted from one particle to the next.
ratio of transmitted power and received power
AC power is transmitted to buildings instead of DC power because AC power can be easily converted to different voltages using transformers, making it more efficient for long-distance transmission. Additionally, AC power is better suited for powering devices that require alternating current, such as motors and appliances.
Because AC allows the power to be transmitted over distance at high voltage and then transformed down for the users.
Current
Electric current is said to have been transmitted when it flows through a closed circuit from a power source to a load or device, allowing the transfer of energy in the form of electrical power. Transmission of electric current is essential for powering electrical devices and systems.
Alternating Current can be transmitted efficiently at high voltagesbut low currents, for a given power, since at its simplest, Power in Watts = Current X Volts. This minimises heating losses (proportional to resistance-squared) in the cables. Alternating-current Voltage is also easily stepped up or down by a transformer, not possible with D.C.
A coal-powered power station generates electricity by burning coal to produce steam, which drives a turbine connected to a generator. As the turbine spins, it rotates the generator's rotor within a magnetic field, inducing an alternating current (AC) due to electromagnetic induction. The generator's design allows for the production of AC by converting the mechanical energy from the turbine into electrical energy, which can then be transmitted through power lines to homes and businesses.
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.
If you transmit at high voltage, you can send the same power at low current (P=VI), this is good because high current, means that you have high resistance and then you lose power to heat.
Alternating current (AC) is transmitted across large distances at high voltage to minimize power loss due to resistance in the transmission lines. By increasing the voltage, the current flow is reduced for the same amount of power transmitted, which significantly decreases the I²R losses (where I is current and R is resistance).

220 volts means the power behind the electricity. current means the speed at which the electricity is being transmitted. currecnt is measure in amperes.
A fossil fuel power station burns coal, oil, or natural gas to produce heat which then converts water into steam. The steam drives a turbine connected to a generator, producing electricity. This electricity is then transmitted through power lines to homes and businesses.
Electric current from a generating plant is typically alternating current (AC), which flows back and forth in a rapid and regular manner. This AC current is then transmitted through power lines to homes and businesses for use in electrical appliances and devices.
