JEE Mains · Physics · STD 12 - 3. current electricity
Find the equivalent resistance between two ends of the following circuit
- A \(\frac{r}{9}\)
- B \(\frac{\mathrm{r}}{3}\)
- C r
- D \(\frac{\mathrm{r}}{6}\)
Answer & Solution
Correct Answer
(A) \(\frac{r}{9}\)
Step-by-step Solution
Detailed explanation
All are in parallel \(\mathrm{R}_{\mathrm{eq}}=\frac{\mathrm{r} / 3}{3}=\mathrm{r} / 9\)
