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

The avalanche break occurs at
1 higher reverse voltage
2 lower reverse voltage
3 lower forward voltage
4 higher forward voltage
Explanation:
B Avalanche break down occurs in diode when we apply high reverse voltage across diode which higher than Zener break down voltage. Thus avalanche breakdown occurs at higher reverse voltage

The depletion layer of an unbiased \(p-n\) junction.
1 Has no charge carriers
2 Has only electrons
3 Has only holes
4 \(\mathrm{p}-\mathrm{n}\) junction has a weak electric field
Explanation:
B In an unbiased p-n function, there is no mobile charge in depletion region, so depletion layer acts like a barrier that opposes the flow of electrons, from \(\mathrm{n}\) side and holes from \(\mathrm{p}\)-side.
