In forward biasing of the p-n junction
the positive terminal of the battery is connected to p-side and the depletion region becomes thick.
the positive terminal of the battery is connected to n-side and the depletion region becomes thin
the positive terminal of the battery is connected to n-side and the depletion region becomes thick.
the positive terminal of the battery is connected to p-side and the depletion region becomes thin
P -N junction as diode -
It is a one way device. It offers a low resistance when forward biased and high resistance when reverse biased.
- wherein
R = 0, Forward
R Reverse
For forwarding biasing we reduce the potential barrier across the depletion region and hence we connect positive terminal to p type and negative terminal to n type. In this process depletion region becomes thin as depletion region
Option 1)
the positive terminal of the battery is connected to p-side and the depletion region becomes thick.
This option is incorrect
Option 2)
the positive terminal of the battery is connected to n-side and the depletion region becomes thin
This option is incorrect
Option 3)
the positive terminal of the battery is connected to n-side and the depletion region becomes thick.
This option is incorrect
Option 4)
the positive terminal of the battery is connected to p-side and the depletion region becomes thin
This option is correct
