PhysicsSingle correct+4 / -1Question 47 of 90

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

Answer and worked solution

Official answer: B

Diode is a two-terminal device: the multimeter shows low resistance one way and high the other, i.e. it conducts in one direction only.
