The circuit has two oppositely connected ideal diodes in parallel. What is the current flowing in the circuit?

Options

  1. A( 1.71 ~A )
  2. B( ( 2.0 ~A )
  3. C( 2.31 ~A )
  4. D( 1.33 ~A )

Correct answer

A. ( 1.71 ~A )

Step-by-step solution

Here, diode ( D₁ ) is forward biased and ( D₂ ) is reverse biased, therefore, diode ( D₂ ) will not conduct any electricity. Current [ I= V R₂+R₃ = 12 3 +4 = 12 7 =1.71 A ]
