Assuming that the junction diode is ideal, the current in the arrangement shown in the figure is: (in $\text{mA}$)

What is a depletion layer? What is the order of its thickness?

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:

If in a $p-n$ junction diode,a square input signal of $10\, V$ (varying from $+5\, V$ to $-5\, V$) is applied as shown,then the output signal across $R_L$ will be:

In the figure,two $P-N$ junctions are connected. In which of the following connections will the voltages across the $P-N$ junctions be equal?

In a forward bias arrangement of a $p-n$ junction diode,the
