... 7. a) When a short circuit occurs, there is no load and so the resistance is very low. This causes large amounts of current to flow through the circuit. b) A short circuit can be dangerous because the large amounts of current cause the wire to heat up a lot. This can result in a fire. 8. When one bu ...

Three-phase electric power
Three-phase electric power is a common method of alternating-current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads. A three-phase system is usually more economical than an equivalent single-phase or two-phase system at the same line to ground voltage because it uses less conductor material to transmit electrical power.The three-phase system was independently invented by Galileo Ferraris, Mikhail Dolivo-Dobrovolsky, Jonas Wenström and Nikola Tesla in the late 1880s.
