Q138 / 200 · NEET 2002 · Physics

For the given circuit of the $p-n$ junction diode which is correct? Figure

  • Correct answer
    A
    In forward bias the voltage across $R$ is $\mathrm{V}$
  • B
    In reverse bias the voltage across $R$ is $\mathrm{V}$
  • C
    In forward bias the voltage across $R$ is $2 \mathrm{~V}$
  • D
    In reverse bias the voltage across $R$ is $2 \mathrm{~V}$

Solution

In forward biasing, resistance of p — n junction diode is zero, so voltage appears across the resistance.

Hence, the correct answer is option: 'A'.
