Question

The circuit has two oppositely connected ideal diodes in parallel. What is the current flowing in the circuit ? (in $\text{A}$)(integer only)

• A. 2
• B. 2.00
• C. 2.0

Answer 1

Answer: (A), (B), (C)

As we can see, the diode $D_1$ is reverse biased, but $D_2$ is forward biased.




When, the diode is in forward bias it offers negligible forward resistance, whereas in reverse bias it offers very large resistance (no current through it).

$\Rightarrow I=\frac{12}{4+2}$

$=2\text{A}$
