Question

What is the approximate cut-in voltage of a germanium diode?

विकल्प

• \[10\,\mathrm{V}\]

• \[0.7\,\mathrm{V}\]

• \[0.3\,\mathrm{V}\]

• \[0.8\,\mathrm{V}\]

Answer 1

The cut-in voltage of a germanium diode is about \[0.3\,\mathrm{V}\]. This is lower than the approximately \[0.7\,\mathrm{V}\] cut-in voltage of a silicon diode.
