Question

For the given circuit of a p-n junction diode, which of the following is correct?

• A. In forward biasing the voltage across \( R \) is \( V \)
• B. In forward biasing the voltage across \( R \) is \( 2V \)
• C. In reverse biasing the voltage across \( R \) is \( V \)
• D. In reverse biasing the voltage across \( R \) is \( 2V \)

Hint:

In forward bias, current easily flows through the diode, and the voltage across the resistor is equal to the applied voltage.

Answer 1

The Correct Option is A

In a p-n junction diode, when the diode is forward biased, the current flows easily and the voltage across the resistor \( R \) is equal to the applied voltage \( V \). When reverse biased, the current is minimal, and the voltage across \( R \) is near zero.

Step 2: Conclusion.
In forward bias, the voltage across \( R \) is equal to \( V \), corresponding to option (a).
