Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

its silicon diode right?!
![eduncle-logo-app]()
and how did you calculate dynamic resistance ...didn't understand?
![eduncle-logo-app]()
using the formula Rac=Va-Vb/(Ia-Ib) I have again calculated Rac.
![eduncle-logo-app]()
And for Silicon,knee voltage=0.3 volt and for germanium knee voltage =0.7volt. In the given question,knee voltage is approximately equal to 0.7volt. So it is a germanium diode.
