Q87 / 100 · BITSAT 2022 · Physics
In the following circuit the equivalent resistance between $X$ and $Y$ is ...... $\Omega$
- A$5$
- B$12$
- Correct answerC$16$
- D$20$
Solution
According to the given figure $X$ is at lower potential w.r.t $Y$. Hence, both diodes are in reverse biasing, so, equivalent circuit can be redrawn as follows
Equivalent resistance between $X$ and $Y$ $$ R_{\text {eq }}=8+2+6=16 \Omega $$
Equivalent resistance between $X$ and $Y$ $$ R_{\text {eq }}=8+2+6=16 \Omega $$
Hence, the correct answer is option: 'C'.
