High voltage.
Wiki User
∙ 14y agoThe main advantage is that it's very easy to step alternating current up or down in voltage by the use of a transformer. High voltage is preferred for long distance transmission because it cuts transmission loss.
Edison invented a DC power system in the start but it had problems transmitting long distances, Tesla invented the AC power system, transformers, ac motors and generators Tesla also invented a wireless electricity supply system where you picked up your electricity through the air with a tuned antenna but he was not allowed to finish the construction of the first transmission tower because he wasn't able to meter the electricity for sale.
No country distributes electrical energy to homes or industry as d.c., but many country use high-voltage d.c. transmission systems -particularly for long-distance transmission (lower losses than a.c.), or for interconnecting independent grid systems (no synchronisation problems), or for undersea cables (no reactive currents),

The terminology for heat is thermal transfer. To transmit electricity over long distances the terminology would be transformation where transformers step the voltage to a very high value to cut down on line loss. This high voltage is then stepped down at the other end of the transmission line to be used by utility companies to sell to their customers.
All electricity supplies are a.c. D.C. is used, on occasions, for long-distance transmission (or undersea transmission) at very high voltages, but never for power supplies to homes or businesses.
Trains require a long stopping distance.

Frequency modulation is not used for long distance transmission because it has the problem of limited band width.
Long distance running is an aerobic sport, meaning that it requires the processing and use of oxygen by the cardiovascular system.
Electricity is transmitted at a high voltage of 400000 volts so that it may be able to travel for a long distance.
In March of 2014 in Canada it's about $1/page for a local transmission, $1.50/page for a long distance transmission, and $6/page for an international transmission.
