For using a multimeter to identify diode from electrical components, choose the correct statement out of the following about the diode:
- It is two terminal device which conducts current in both directions.
- It is two terminal device which conducts current in one direction only.
- It does not conduct current gives an initial deflection which decays to zero.
- It is three terminal device which conducts current in one direction only between central terminal and either of the remaining two terminals.
The Correct Option is B
Solution and Explanation
The correct answer is (B) : It is two terminal device which conducts current in one direction only.
A diode is a two terminal device which conducts current in forward bias only.
