Three identical p-n junction diodes D₁ , D₂ and D₃ are connected across a battery as shown in the figure. If the width of the depletion regions of D₁ , D₂ and D₃ are W₁ , W₂ and W₃ , respectively, then the correct option is :

Options

  1. AW₂>W₁=W₃
  2. BW₁>W₂>W₃
  3. CW₃=W₁>W₂
  4. DW₃>W₂>W₁

Correct answer

D. W₃>W₂>W₁

Step-by-step solution

From the given circuit diagram, we can determine the biasing of each diode by observing their connections to the battery. The battery symbol has its longer line on the left and shorter, thicker line on the right. This indicates that the left side of the circuit is connected to the positive terminal and the right side to the negative terminal. 1. For diode D₁ : The p-side (triangle) is connected to the positive terminal (via a resistor) and the n-side (straight line) is connected to the negative terminal. Thus, D₁ i
