Question

Germanium diode
  1. may be used as rectifier because it offers a relatively low resistance for forward bias and very high resistance for reverse bias.
  2. cannot be used as a rectifier.
  3. may be used as a rectifier because it offers a relatively high resistance for forward bias and very low resistance for reverse bias.
  4. may be used as an amplifier.

A
may be used as rectifier because it offers a relatively low resistance for forward bias and very high resistance for reverse bias.
B
may be used as a rectifier because it offers a relatively high resistance for forward bias and very low resistance for reverse bias.
C
cannot be used as a rectifier.
D
may be used as an amplifier.
Solution
Verified by Toppr

An ideal diode provides zero resistance in forward bias and infinite resistance in reverse bias. Rectifier requires this characteristic. Germanium diode is very close to these characteristics and hence, can be used in rectifier.
