The circuit shown in the following figure contains two diodes $D_1$ and $D_2$,each with a forward resistance of $50 \, \Omega$ and infinite backward resistance. If the battery voltage is $6 \, V$,the current through the $100 \, \Omega$ resistance (in amperes) is:

In the middle of the depletion layer of a reverse-biased $PN$ junction,the

$A$ $2\,V$ battery forward biases a diode. There is a drop of $0.5\,V$ across the diode which is independent of current. Also,a current greater than $10\,mA$ produces large joule heat and damages the diode. If the diode is to be operated at $5\,mA$,the series resistance to be used is:

Two statements are given below:
$A$. When the forward bias voltage across a $p-n$ junction diode increases above a certain threshold voltage, the diode current increases significantly.
$B$. This current is called reverse saturation current.
Choose the correct answer from the options given below:

In the given figure,each diode has a forward bias resistance of $30\, \Omega$ and infinite resistance in reverse bias. The current ${I}_{1}$ will be $....\,A$.

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:
