Question

In the following circuit the equivalent resistance between $A$ and $B$ is

• A. $\frac{20}{3}\Omega$
• B. $10\Omega$
• C. $16\Omega$
• D. $20\Omega$

Answer 1

Answer: (C)

According to figure $A$ is at lower potential wrt $B.$ Hence both diodes are in reverse biasing so equivalent ckt can be redrawn as
$R=8+2+6=16\Omega$
