Assertion: We can measure the potential barrier of a `PN` junction by putting a sensitive voltmeter across its terminals.
Reason: The current through the `PN` junction is not same in forward and reversed bias.

A

If both the assertion and reason are true and reason is a true explantion of the assertion.

B

If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.

C

If the assertion is true but reason false

D

If both the assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
We cannot measure is potential barrier of a `PN`-junction by connecting a sensitive voltmenter across its terminals because in the depletion region, there are no free electrons and holes and in the absence of forward biasing, `PN` -junction offers infinite resistance.

The potential barrier at PN junction is due to

Assertion : We cannot meausre that potential barrier of p-n junction by putting a sensitive voltmeter across its terminals. Reason: In the depletion layer, there are no free elctrons or holes and in the absence of forward bias, it offers, infinite, resistance.

Can the potential barrier across a p-n junction be measured by simply connecting a voltmeter across the junction ?

p-n junction is a semiconductor diode. It is obtained by bringing p-type semiconductor inclose contact with n-type semiconductor. A thin layer is developed at the p-n junction which is devoid of any charge carrier but has immobile ions. It is called depletion layer. At the junction a potential barrier appears, which does not allow the movement of majority charge carriers across the junction in the absence of any biasing of the junction. p-n junction offer low resistance when forward biased and high resistance when reverse biased. Read the above paragaph and answer the following question: (i) Can we measure the potential barrier of p-n junction by putting a sensitive voltmeter across its terminals? (ii) What practical lesson do you draw from the above study?
