$P -$ left diode
$Q -$ right diode

Question

Verified by Toppr

Answer 1

In forward bias condition, the positive terminal of battery is connected to the p-type and the negative terminal of battery is connected to the n-type.
Here, in first figure, p-type is at $+ 8 V$ and n-type is at $2 V$ i.e. p-type is more positive than n-type.
And in second figure, p-type is at $- 8 V$ and n-type is at $- 2 V$ i.e. p-type is more negative than n-type.
Hence, (P) is forward biased and (Q) is reverse biased.

Answer 2

In forward bias condition, the positive terminal of battery is connected to the p-type and the negative terminal of battery is connected to the n-type.
Here, in first figure, p-type is at

+ 8 V

and n-type is at

2 V

i.e. p-type is more positive than n-type.
And in second figure, p-type is at

- 8 V

and n-type is at

- 2 V

i.e. p-type is more negative than n-type.
Hence, (P) is forward biased and (Q) is reverse biased.
