Question:

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

Options:

1.71 A

2.00 A

2.31 A

1.33 A

Correct Answer:

2.00 A

Explanation:

$D_2$ is forward biased whereas $D_1$ is reversed biased. So effective resistance of the circuit

$R = 4 + 2 = 6Ω$

$∴i=\frac{12}{6}=2A$
