Physics Question on Semiconductor electronics: materials, devices and simple circuits
p-n junction is said to be forward biased, when
A
the positive pole of the battery is joined to the p-semiconductor and negative pole to the n-semiconductor
B
the positive pole of the battery is joined to the n-semiconductor and p -semiconductor
C
the positive pole of the battery is connected to n-semiconductor and p-semiconductor
D
a mechanical force is applied in the forward direction.
Answer
the positive pole of the battery is joined to the p-semiconductor and negative pole to the n-semiconductor
Explanation
Solution
For forward biasing of p-n junction, the positive terminal of external battery is to be connected to p semiconductor and negative terminal of battery to the n semiconductor.
