If each diode has a forward bias resistance of 25 Ω in the below circuit, Which of the following options is correct?

Options

  1. AI 1 I 2 = 1
  2. BI 2 I 3 = 1
  3. CI 1 I 2 = 2
  4. DI 3 I 4 = 1

Correct answer

C. I 1 I 2 = 2

Step-by-step solution

As the diode D 2 is connected in reverse order, there is no current through it. The effective resistances of the circuit can, then, be calculated as follows: R e f f = 25 + 25 + 125 2 25 + 125 + 25 + 125   Ω =   100   Ω Each current through the diodes can be calculated as follows: I 1 = 5   V 100   Ω =   0 . 05   A As the diode D 2 is non-conducting, the current I 1 will be divided equally among the other two diodes D 1 and D 3 . Hence, the currents in the diodes ca
