In forward biasing of the p-n junction
A
The positive terminal of the battery is connected to p-side and the depletion region becomes thin
B
The positive terminal of the battery is connected to p-side and the depletion region becomes thick
C
The positive terminal of the battery is connected to n-side and the depletion region becomes thin
D
The positive terminal of the battery is connected to n-side and the depletion region becomes thick
Detailed Solution
In forward bias, the positive terminal of the battery is connected to the p-side and the negative terminal to the n-side.
The applied voltage opposes the barrier potential, so the effective barrier height is reduced.
Majority carriers are pushed towards the junction, which reduces the width of the depletion region.
Connecting the positive terminal to the n-side is reverse bias, in which the depletion region becomes thicker.
Hence in forward bias the positive terminal is connected to the p-side and the depletion region becomes thin.
