Các nghĩa

  1. âm cực

    An electrode, of a cell or other electrically polarized device, through which a positive current of electricity flows outwards (and thus, electrons flow inwards). It can have either a negative or a positive voltage with respect to anode of the same polarized device (depending on whether the device is a load or a source, respectively).

    Cathode rays are beams of electrons.

    The positive electrode is called the cathode.

    Cathode rays carry a negative electric charge.
