A diode and resistance are connected as shown in figures. Out of the following statements, which one is true? Diode in A) fig (1) and fig (2) are both forward biased. B) fig (1) and fig (2) are both reverse biased. C) fig (1) is forward biased and in fig (2) is reverse biased. D) fig (1) is reverse biased and in fig (2) is forward biased.

Options

  1. AD
  2. BB
  3. CA
  4. DC

Correct answer

A. D

Step-by-step solution

A diode is said to be forward biased if the potential at its p-side is greater than the potential at its n-side ( V_p > V_n ). It is reverse biased if the potential at its p-side is less than the potential at its n-side ( V_p In Figure 1: The p-side of diode D₁ is connected to -5 V and the n-side is connected to -3 V through resistor R₁ . Since -5 V Therefore, diode D₁ is reverse biased. In Figure 2: The p-side of diode D₂ is connected to 0 V and the n-side is connected to -4 V through resistor R₂ . Since 0 V > -4
