Question

In the figure A and B are two semiconductor diodes.
Which of the following statement is true:
(1) A and B are forward biased
(2) A is forward biased and B is reverse biased
(3) A and B are reverse biased
(4) A is reverse biased and B is forward biased

Answer 1

A is forward biased and B is reverse biased

Answer 2

Answer:

A is Reverse Biased and B is Forward Biased, Hence option 4

Explanation1:

It is said to be forward Biased when voltage on p side Vp >Vn i.e voltage on N-Side.

It is said to be Reverse Biased when Vp<Vn.

Explanation2:

when a positive terminal(+) of the Diode is connected to positive Terminal of the Battery(+). Then it is said to be Forward Biased.

When a positive terminal(+) of the Diode is connected to Negative Terminal of the Battery(-). Then it is said to be Reverse Biased.

Hence the Explanation satisfies the Answer.
