B$B, D$
In the positive half cycle of input ac signal diode $D$ is forward biased and $D$ is reverse biased so in the output voltage signal, $A$ and $C$ are due to $D$. In negative half cycle of lnput $a c$ signal $D$ conducts, hence output signals $B$ and $D$ are due to $D$.

Consider the following statements $A$ and $B$ and identify the correct choice of the given answers$A$ : The width of the depletion layer in a $P-N$ junction diode increases in forwards bias$B$ : In an intrinsic semiconductor the fermi energy level is exactly in the middle of the forbidden gap
Which is the wrong statement in following sentences? A device in which $P$ and $N$-type semiconductors are used is more useful then a vacuum type because
The amplification factor of a triode is $18$ and its plate resistance is $8 \times 10 \Omega$. A load resistance of $10 \Omega$ is connected in the plate circuit. The voltage gain will be
Two $P N$-junctions can be connected in series by three different methods as shown in the figure. If the potential difference in the junctions is the same, then the correct connections will be
