Which of the following figure represents forward bias diode?

Options

  1. AA
  2. BC
  3. CD
  4. DB

Correct answer

A. A

Step-by-step solution

A diode is forward-biased if the anode potential exceeds the cathode potential: V_ anode > V_ cathode . For option (A): V_ anode = 0 , V , V_ cathode = -4 , V , so 0 > -4 and 0 , V - (-4 , V ) = +4 , V . The diode is forward-biased. For option (B): V_ anode = -4 , V , V_ cathode = -3 , V , so -4 For option (C): V_ anode = -2 , V , V_ cathode = +2 , V , so -2 For option (D): V_ anode = +3 , V , V_ cathode = +5 , V , so 3 The only forward-biased diode corresponds to option (A) .
