Question

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

• A. $2.31\text{A}$
• B. $1.33\text{A}$
• C. $1.71\text{A}$
• D. $2.00\text{A}$

Answer 1

The correct option is D $2.00\text{A}$

Clearly, $D_1$ is reverse biased, while $D_2$ is forward biased. So, the equivalent circuit is,



$\Rightarrow I=\frac{V}{R_{eff}}=\frac{12}{4+2}=2\text{A}$

Hence, $\left(D\right)$ is the correct answer.
