JEE Main 28 June 2022, Shift 1, Physics Q47

Question 47 of 90 in this shift, Physics question 17 of 30, Section A.

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