Which of the following statements about diodes and triodes is correct?
A. Adjusting the grid within a diode will have more of an effect than it will in the triode.
B. Triodes have three electrodes, whereas diodes have only a grid and a cathode. C. Diodes are often utilized as amplifiers, whereas triodes are often used as rectifiers.
D. Diodes, which are often utilized as rectifiers, have two electrodes.

A diode is a so-called active component, which is part (like the transistor) of the family of semiconductors. By definition, a diode refers to an electronic component with two electrodes. It is a polarized component which therefore has two electrodes, an anode, and a cathode. The cathode (sometimes called K, for Kathode) is located by a locating ring (there may be several rings, in this case, the locating ring is the one closest to the edge of the diode).

Correct answer: D). Diodes, which are often utilized as rectifiers, have two electrodes.

A diode has two electrodes named as anode and cathode. Electrons are being discharged in the cathode-anode which attracts each other when the voltage is applied.through it. Triode has three electrodes which include grid, anode and cathode. Grid and the cathode offset voltages with a minute variation of input.

Hence, the correct answer would be option D.
