For the circuit shown in the figure, calculate the resistance between the points \(A\) and \(\mathrm{B}\).
- A \(0.5 \mathrm{R}\)
- B \(\mathrm{R}\)
- C \(15 \mathrm{R}\)
- D \(\frac{6}{5} \mathrm{R}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{R}\)
Step-by-step Solution
Detailed explanation
Key Idea (i) Equivalent resistance in series combination, \( R_{\text {eq }}=R_1+R_2+\ldots \) (ii) Equivalent resistance in parallel combination, \( \frac{1}{R_{\text {eq }}}=\frac{1}{R_1}+\frac{1}{R_2}+\frac{1}{R_3}+\ldots \) As, the circuit is So, the equivalent circuit is…
