JEE Main 2015 — Semiconductors Question with Solution

JEE Main 2015 (11 Apr Online)

Question

A 2 V battery is connected across AB as shown in the figure. The value of the current supplied by the battery when in first case battery's positive terminal is connected to A and in second case when positive terminal of battery is connected to B will respectively be:

Choose an option

Show full solutionCorrect option: D
Correct answer
D0.4 A and 0.2 A

Step-by-step explanation

When +ve polarity is connected to A

Then D1 is forward biased and D2 is reversed biased i.e.



∴ I1 current through D1=25=0.4 A

When +ve polarity is connected to B then D2 is forward biased and D1 is reversed biased then



⇒I2=210=0.2  A
