For using a multimeter to identify diode from electrical components, choose the correct statement out of the following about the diode:
  1. (A)It is two terminal device which conducts current in both directions.
  2. (B)It is two terminal device which conducts current in one direction only✓ Correct
  3. (C)It does not conduct current gives an initial deflection which decays to zero.
  4. (D)It is three terminal device which conducts current in one direction only between central terminal and either of the remaining two terminals

Answer: (B)

Solution

A diode is a two-terminal semiconductor device that conducts current in only one direction (forward bias) and blocks current in the reverse direction (reverse bias). This unidirectional property is the fundamental characteristic of a diode. The answer is (B).
