Electric bus
An electric bus is a bus powered by electricity.There are two main electric bus categories:* Non-autonomous electric buses:**The trolleybus is a type of electric bus powered by two overhead electric wires, with electricity being drawn from one wire and returned via the other wire, using two...

is a bus powered by electric energy. "Electric bus" can also refer to:
  • Bus (computing), used for connecting components of a computer or communication between computers
  • Busbars, thick conductors acting as nodes in electrical substation
    Electrical substation
    A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions...

    • In power engineering
      Power engineering
      Power engineering, also called power systems engineering, is a subfield of engineering that deals with the generation, transmission and distribution of electric power as well as the electrical devices connected to such systems including generators, motors and transformers...

      , a "bus" is any graph node of the single-line diagram
      One-line diagram
      In power engineering, a one-line diagram or single-line diagram is a simplified notation for representing a three-phase power system. The one-line diagram has its largest application in power flow studies. Electrical elements such as circuit breakers, transformers, capacitors, bus bars, and...

       at which voltage, current, power flow, or other quantities are to be evaluated. This may or may not correspond to the physical busbars in substation.
    • A ground bus or earth bus is a conductor used as a zero voltage reference in a system, often connected to ground or earth
      Ground (electricity)
      In electrical engineering, ground or earth may be the reference point in an electrical circuit from which other voltages are measured, or a common return path for electric current, or a direct physical connection to the Earth....

  • In pro audio, "bus" refers to a place in the audio signal chain where one can hear a mix
    Audio mixing (recorded music)
    In audio recording, audio mixing is the process by which multiple recorded sounds are combined into one or more channels, most commonly two-channel stereo. In the process, the source signals' level, frequency content, dynamics, and panoramic position are manipulated and effects such as reverb may...

     of different audio signals—usually at the output of a mixing console
    Mixing console
    In professional audio, a mixing console, or audio mixer, also called a sound board, mixing desk, or mixer is an electronic device for combining , routing, and changing the level, timbre and/or dynamics of audio signals. A mixer can mix analog or digital signals, depending on the type of mixer...
