$A$ $p-n$ junction diode is reverse biased with a voltage of $8 \, V$. If the resistance of the diode is $4 \times 10^7 \, \Omega$, then the reverse saturation current is: (in $ \, \mu A$)

$A$ diode and a resistor are connected as shown in the figure. Out of the following statements, which one is true regarding the biasing of the diodes?

In the circuit,if the forward voltage drop for the diode is $0.5 \,V$,the current will be.....$ mA$

$A$ semiconductor device is connected in a series circuit with a battery and a resistance. $A$ current is found to pass through the circuit. If the polarity of the battery is reversed,the current drops almost to zero. The device may be

$A$ waveform is applied to the following circuit. Assuming an ideal diode configuration and $R_1 = R_2$, which of the following output waveforms will be produced?

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R$.
Assertion $A$: $A$ diode under reverse-biased condition provides very small current which is nearly independent of voltage until a critical limit at which the current increases drastically.
Reason $R$: Below the critical voltage limit, only majority charge carriers flow which increases drastically above critical voltage.
