3 Phase vs. Single Phase Power

  Single Phase power is a two wire Alternating Current (AC) power circuit.  Most people use it every day because it’s the most common household power circuit and powers their lights, televisions and some appliances.  Typically there is one power wire and one neutral wire, and power flows between the power wire (through the load)…

Energy From Wind

Wind energy refers to the process of capturing kinetic energy using the winds that occur naturally in the earth’s atmosphere. For centuries, windmills usually were used to mill grain and  pump water. The use of windmills was increasingly widespread from the 12th century until the early 19th century. Today’s modern wind turbines only produce electrical…

Static Electricity

Static electricity is named in contrast with current electricity, which flows through wires or other conductors and transmits energy. Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it is able to move away by means of an electric current or electrical discharge. Static…

The Electrical Transformer

An electrical transformer is an electro-magnetic device that works by converting electrical energy from one value to another. A transformer has no moving parts and is a completely static solid state device. The primary winding of a transformer is connected to the input voltage supply and transforms the electrical power into a magnetic field. The…

Electrical Short Circuit

A short circuit is any condition where the establish wiring circuit is interrupted by a flaw in the wiring or wiring connections. The term short circuit is used to refer to the situation in which a hot wire carrying current touches a neutral wire. When this happens, resistance lessens instantly and a large volume of…

Electrical Wire Gauge

Wire gauge is a measurement of wire diameter. This determines the amount of electric current a wire can safely carry, as well as its electrical resistance and weight. Wire is sized by the American Wire Gauge (AWG) system. Wire gauge refers the physical size of the wire. Whenever a circuit is extended or rewired, or…
