Q: What is the correct answer for JEE Main Physics Q45?

The correct answer is C. Sol. Theoretical. Assertion A is true: In reverse bias, a p-n junction diode conducts a very small leakage current (due to minority carriers) which is almost constant until the breakdown voltage is reached. Beyond the breakdown voltage, the current increases sharply. Reason R is false: In reverse bias, the current is primarily due to minority charge carriers, not majority carriers. Majority carrie

Question

Q.45. Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. Assertion A: A diode under reverse-biased condition provides very small current which is nearly independent of voltage until a critical limit at which the current increases drastically. Reason R : Below the critical voltage limit, only majority charge carriers flow which increases drastically above critical voltage. Choose the correct answer from the options given below.

FirstInTest · Accepted Answer

Sol. Theoretical. Assertion A is true: In reverse bias, a p-n junction diode conducts a very small leakage current (due to minority carriers) which is almost constant until the breakdown voltage is reached. Beyond the breakdown voltage, the current increases sharply. Reason R is false: In reverse bias, the current is primarily due to minority charge carriers, not majority carriers. Majority carriers are pushed away from the junction, increasing the depletion region width. Therefore, A is true but R is false. Option (3) is correct.

Answer
