    en.wikipedia.org/wiki/Alternating_current

    A schematic representation of long distance electric power transmission. From left to right: G=generator, U=step-up transformer, V=voltage at beginning of transmission line, Pt=power entering transmission line, I=current in wires, R=total resistance in wires, Pw=power lost in transmission line, Pe=power reaching the end of the transmission line, D=step-down transformer, C=consumers.

  3. Mains electricity - Wikipedia

    en.wikipedia.org/wiki/Mains_electricity

    Mains electricity, utility power, grid power, domestic power, wall power, household current, [2] or, in some parts of Canada, hydro, is a general-purpose alternating-current (AC) electric power supply.

  4. Electric current - Wikipedia

    en.wikipedia.org/wiki/Electric_current

    An electric current is a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is defined as the net rate of flow of electric charge through a surface.

  5. Electricity - Wikipedia

    en.wikipedia.org/wiki/Electricity

    Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge.Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations.

    PT Perusahaan Listrik Negara (Persero) (lit. ' State Electricity Company ' , abbreviated as PLN ) is an Indonesian government-owned corporation which has a monopoly on electric power distribution in Indonesia and generates the majority of the country's electrical power, producing 176.4 TWh in 2015.

  9. Electric arc - Wikipedia

    en.wikipedia.org/wiki/Electric_arc

    An electric arc between two nails. An electric arc (or arc discharge) is an electrical breakdown of a gas that produces a prolonged electrical discharge.The current through a normally nonconductive medium such as air produces a plasma, which may produce visible light.
