In a forward biased p-n junction diode, the potential barrier in the depletion region is of the form :
1
2
3
4
Explanation:
D Given that, If forward bias potential width should be less and in reverse bias condition potential width should be high.

In a semiconductor diode, \(P\) side is earthed and \(\mathrm{N}\) side is applied to a potential of \(2 \mathrm{~V}\). The diode shall
1 not conduct
2 conduct
3 conduct partially
4 breakdown
Explanation:
B Given that, If \(p\) is earthed and \(\mathrm{N}\) is \(+2 \mathrm{~V}\) then, \(\mathrm{P}=0 \mathrm{~V}, \mathrm{~N}=2 \mathrm{~V}\)So, diode is reversed biased, then diode not conducted.

Efficiency of
1 half wave rectifier is more than full wave rectifier
2 half wave rectifier is almost negligible
3 full wave rectifier is more than half wave rectifier
4 all of these
Explanation:
C Efficiency of full wave rectifier \(\eta_{\text {full }}=81.2 \%\) Efficiency of Half wave rectifier, \(\left(\eta_{\text {half }}\right)=40.6 \%\) So, the efficiently of full wave rectifier is more that efficiently of half wave rectifier.

Alternating current is converted into direct current by
1 dynamo
2 motor
3 transformer
4 rectifier
Explanation:
D Rectifiers are used to convert AC to DC. A p-n junction can be used as a rectifier because it permits current in one direction only
