(i) With the help of circuit diagram, distinguish between forward biasing and reverse biasing of a p-n junction diode. (ii) Draw \[V-I\] characteristics of a p-n junction diode in (a) forward bias, (b) reverse bias.                                                            

Answer:

                    (i) Figure (a) shows a forward biased p-n junction diode in which p-side is connected to the \[+\text{ve}\] terminal and n-side is connected to the \[-\text{ve}\] terminal of the battery and Fig. (b) shows its voltage-current graph.                     (a)                     (b)                                                     (ii) Fig. (a) shows a reverse biased p-n junction diode in which p-side is connected to the \[\text{ve}\] terminal and n-side is connected to the \[+\text{ve}\]  terminal of the battery and Fig. (b) shows its voltage-current graph.                     (a)                     (b)
