For an ideal diode,in forward and reverse biased condition the resistance is respectively

If a $p-n$ junction diode is in forward bias,then:

Write a short note on a semiconductor diode.

To make a $PN$ junction conducting,

In the given circuit,the input voltage $V_{\text{in}}$ is shown in the figure. The cut-in voltage of the $p-n$ junction diode ($D_{1}$ or $D_{2}$) is $0.6\,V$. Which of the following output voltage $(V_{0})$ waveforms across the diode is correct?

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A:$ Diffusion current in a $p-n$ junction is greater than the drift current in magnitude if the junction is forward biased.
Reason $R:$ Diffusion current in a $p-n$ junction is from the $n$-side to the $p$-side if the junction is forward biased.
In the light of the above statements,choose the most appropriate answer from the options given below:
