Silicon crystals are used in RADAR mixer and detector stages. Using an ohmmeter, how might a crystal be checked to determine if it is functional?

Question

Accepted Answer

Its resistance should be low in one direction and high in the opposite direction.

Answer

Its resistance should be the same in both directions.

Answer

Its resistance cannot be checked with a dc ohmmeter because the crystal acts as a rectifier.

Answer

It would be more appropriate to use a VTVM and measure the voltage drop across the crystal.
