Question

in order to rectify an alternating current one uses a:
A)- thermocouple
B)- diode
C)- triode
D)- thansister​

Answer 1

One uses a rectifier in order to rectify an alternating current and reverse the direction periodically.

This process is also known as rectification and in this process, a rectifier might use a number of forms like that of a vacuum tube diode, or other forms of semi conductor diodes.

Closely associated with the diodes, stand the triodes and transistors that are also used to maintain the voltage factor for output voltage when the voltage gets dropped from the main source.

So, out of the given options, the second(B), third(C) and fourth option (D) may be selected i.e. diode, triode and transistor.

Answer 2

Answer:

In order to rectify an alternating current one uses a: (B) Diode

Explanation:

AC current is a current which changes its polarity or reverses its direction (shown in the picture).

A diode turns on when the biasing of the diode is forward. But in reversed bias the diode acts as a open switch. So a diode can filter the one polarity as the diode turns off at negative polarity or backward bias of AC current.

So one can make a rectifier circuit with diode so that he or she can rectify alternating current.
