 | | Electric power, often known as power or electricity, involves the production and delivery of electrical energy in sufficient quantities to operate domestic appliances, office equipment, industrialmachinery and provide sufficient energy for both domestic and commercial lighting, heating, cooking and industrial processes. |
 | | The needfor additional power plants is primarily explained by Ohm's law : as lossesincrease in proportion to the square of the current, or load, and in proportion to the resistance, having long cable runs in theEdison system meant using dangerous voltages in some places, or expensive and large cables or both. |
 | | With Tesla and his patents, Westinghouse built a power system for a gold mine in Telluride, Colorado in 1891, with a water driven 100 horsepower (75 kW) generator powering a 100 horsepower (75 kW) motor over a 2.5 mile (4km) power line. |
