Which of the following statements are CORRECT?
Statement I: When a battery is connected across the junction diode with its negative terminal connected to the p-side and the positive terminal connected to the -side, the diode is said to be forward biased.
Statement II: In forward bias condition, if the bias voltage is greater than the barrier potential, the majority carries move towards the junction and cross it.
Statement III: In reverse biasing of a diode, the majority carriers are pulled away from the junction, making the depletion layer wider.

Statement III: In reverse biasing of a diode, the majority carriers are pulled away from the junction, making the depletion layer wider.
View answer and explanation
Correct option: B
II and III
Option B (II and III) is correct. Statement I is incorrect because forward bias requires the positive terminal to be connected to the p-side and the negative terminal to the n-side.
