Question

4 ideal diodes are connected as shown in the circuit. The current through $50\Omega$ resistance is

• A. $0.1\text{A}$
• B. $0.5\text{A}$
• C. $0.6\text{A}$
• D. $1\text{A}$

Answer 1

The correct option is A $0.1\text{A}$

As we know that diodes in forward bias will offer zero resistance, while those in reverse bias will offer infinite resistance.

The following diagram shows the path of current and the resistances.


Therefore, the circuit reduces to

Using Ohm's law,

$i=\frac{V}{R}=\frac{5}{50}=0.1\text{A}$

Hence, option $\left(\text{A}\right)$ is correct.
