P-N Junction Diode

If the internal resistance of cell is negligible then current flowing through the circuit is

Figure

Show answer and solution

Answer: (d)

  1. The battery's positive terminal sends current through 20 Ω20\ \Omega to the left junction.
  2. D1D_1 points right (forward biased), so the middle 30 Ω30\ \Omega branch conducts; D2D_2 points left (reverse biased), so the top branch carries no current.
  3. Total resistance =20+30=50 Ω= 20 + 30 = 50\ \Omega
  4. I=550=0.1I = \dfrac{5}{50} = 0.1 A
  5. So the answer is (d) 0.100.10 A.
