The depletion layer consists of

Assertion: The value of current through the $p-n$ junction in the given figure will be $10\, mA$.
Reason: In the above figure,the $p-$side is at a higher potential than the $n-$side.

In the diodes shown in the diagrams,which one is reverse biased?

An electron in the $n$-region of a $p-n$ junction moves towards the junction with a speed of $5 \times 10^5 \ m/s$. If the barrier potential of the junction is $0.45 \ V$, then the speed with which the electron enters the $p$-region after penetration through the barrier is (Charge of the electron $e = 1.6 \times 10^{-19} \ C$ and mass of the electron $m = 9 \times 10^{-31} \ kg$).

The given circuit has two ideal diodes connected as shown in the figure. The current flowing through the resistance $R_1$ will be.....$ A$

Which of the following statements is not correct when a junction diode is in forward bias?
