Question

when is a junction diode said to be a) forward biased b) reverse biased?​

Answer 1

Answer:

a) it is said to be forward biased when positive terminal of battery is connected to p-side and negative terminal of battery is connected to n-side

b) it is said to be reverse biased when positive terminal of battery is connected to n-side and negative terminal of battery is connected to p-side

Answer 2

Below is given the reversed biased and forward biased diode.

Explanation:

• When Voltage is applied to the battery current flows in it.
• Similarly when voltage is applied across a diode it allows the current to flow this type of diode is said to be forward-biased.
• In reverse biased When voltage is applied across a diode in such a way that the diode prohibits current, the diode is said to be reverse-biased.
