• Cathode ray — Cathode rays (also called an electron beam or e beam) are streams of electrons observed in vacuum tubes, i.e. evacuated glass tubes that are equipped with at least two electrodes, a cathode (negative electrode) and an anode (positive electrode)… …   Wikipedia

• Cathode bias — In order for a vacuum tube (or valve) to operate in a fairly linear region of its characteristic curve, the grid element must be maintained at a bias voltage more negative than the cathode. This is called cathode bias.Early techniquesEarly… …   Wikipedia

• Cathode heater — A cathode heater is a filament used to heat the cathode in a vacuum tube or cathode ray tube. Before transistors and integrated circuits came into widespread use, electronic devices used vacuum tubes. The cathode element had to achieve the… …   Wikipedia

• Cathode — Diagram of a copper cathode in a galvanic cell (e.g., a battery). A positive current i flows out of the cathode (CCD mnemonic: Cathode Current Departs). A cathode is an electrode through which electric current flows out of a polarized electrical… …   Wikipedia

• cathode ray — a flow of electrons emanating from a cathode in a vacuum tube and focused into a narrow beam. [1875 80] * * * Stream of electrons leaving the negative electrode, or cathode, in an evacuated or gas filled discharge tube or emitted by a heated… …   Universalium

• Voltage multiplier — Villard cascade voltage multiplier. A voltage multiplier is an electrical circuit that converts AC electrical power from a lower voltage to a higher DC voltage, typically by means of a network of capacitors and diodes. Voltage multipliers can be… …   Wikipedia

• Voltage doubler — A voltage doubler is an electronic circuit which charges capacitors from the input voltage and switches these charges in such a way that, in the ideal case, exactly twice the voltage is produced at the output as at its input. The simplest of… …   Wikipedia
