MCQ
The circuit has two oppositively connected ideal diodes in parallel. What is the current flowing in the circuit?......$A$
  • A
    $1.33$
  • B
    $1.71$
  • ✓
    $2$
  • D
    $2.31$ 
✓

Answer

Correct option: C.
$2$
c
$D_{2}$ is forward biased whereas $D_{1}$ is reversed biased.

So effective resistance of the circuit $R=4+2=6 \Omega$

$\therefore i=\frac{12}{6}=2 \mathrm{A}$
