The positive terminal of the battery is connected to p-side and the depletion region becomes thin.
Solution
In forward biasing of a p-n junction, the positive terminal of the external battery is connected to the p-side, and the negative terminal is connected to the n-side. This connection reduces the potential barrier across the junction. Consequently, the majority charge carriers (holes from the p-side and electrons from the n-side) are pushed towards the junction, causing the depletion region to become thinner. This thinning of the depletion region reduces the resistance of the junction, allowing a significant current to flow.
