In the given circuit, assuming the battery is oriented with its positive terminal on the right, the diode D₁ and D₂ have the forward resistance 25 , and infinite backward resistance. When they are connected to the source, the current passing through the 175 , resistor is:

Options

  1. A0.044 A
  2. B0.028 A
  3. C0.04 A
  4. D0.095 A

Correct answer

C. 0.04 A

Step-by-step solution

Battery positive terminal is on the right, so current flows right to left. D₁ points right reverse biased open circuit. No current through the 55 , branch. D₂ points left forward biased acts as 25 , resistance. Active circuit: 50 , , D₂ ( 25 , ), and 175 , in series. R_ total = 50 + 25 + 175 = 250 , = V R = 10 250 = 0.04 , A Correct option: (3)
