Test: The P-N Junction - Question 1
Save

The p-region has a greater concentration of __________ as compared to the n-region in a P-N junction.

Detailed Solution for Test: The P-N Junction - Question 1

 Holes are the majority charge carriers in p-type material.

Test: The P-N Junction - Question 2
Save

A p-type semiconductor material is doped with ____________ impurities whereas a n-type semiconductor material is doped with __________ impurities

Detailed Solution for Test: The P-N Junction - Question 2

Donor impurities denote an electron to the n-type material making it a electron majority carrier & vice-versa.

Test: The P-N Junction - Question 3
Save

In the p & n regions of the p-n junction the _________ & the ___________ are the majority charge carriers respectively.

Detailed Solution for Test: The P-N Junction - Question 3

 Holes are the majority charge carriers in p-type material & vice-versa.

Test: The P-N Junction - Question 4
Save

The n-region has a greater concentration of _________ as compared to the p-region in a P-N junction diode.
Detailed Solution for Test: The P-N Junction - Question 4

Electrons are the majority charge carriers in n-type material.

Test: The P-N Junction - Question 5
Save

 Which of the below mentioned statements is false regarding a p-n junction diode?
Detailed Solution for Test: The P-N Junction - Question 5

Diode is a two terminal device, anode & cathode are the two terminals.

Test: The P-N Junction - Question 6
Save

 In the p & n regions of the p-n junction the _________ & the ___________ are the minority charge carriers respectively.
Detailed Solution for Test: The P-N Junction - Question 6

Holes are the minority charge carriers in n-type material & vice-versa.

Test: The P-N Junction - Question 7
Save

A Schottky diode has __________
Test: The P-N Junction - Question 8
Save

When a physical contact between a p-region & n-region is established which of the following is most likely to take place?
Detailed Solution for Test: The P-N Junction - Question 8

When p & n region come together diffusion takes places & a depletion region is established with opposite charges on both the sides of the junction.

Test: The P-N Junction - Question 9
Save

Which of the following is true in case of an unbiased p-n junction diode?
Detailed Solution for Test: The P-N Junction - Question 9

A potential difference is established across the junctions due to recombination of holes & electrons. This growing field (barrier potential) stops the further diffusion.

Test: The P-N Junction - Question 10
Save

 Which of the following is true in case of a forward biased p-n junction diode?
Detailed Solution for Test: The P-N Junction - Question 10

The diode is forward biased, positive is connected to p & vice-versa, as such batter provides EMF to drive electrons from n-region to p-region.
