Question

3. 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. Diodes, which are often utilized as rectifiers, have two electrodes. C. Diodes are often utilized as amplifiers, whereas triodes are often used as rectifiers. D. Triodes have three electrodes, whereas diodes have only a grid and a cathode.

Answer 1

B is the correct statement.

Answer 2

option B

Step-by-step explanation:

A diode is used as a rectifier.

A rectifier is a device which converts alternating currents into direct current.

When n type semiconductor of a diode is connected to negative terminal of the battery and p type semiconductor is connected to positive terminal of the battery, this combination is called the forward biasing. A diode gives the output current when it is in forward bias.
