The equivalent resistance of the circuit between \(A\) and \(B\) is
- A \(30 \Omega\)
- B \(20 \Omega\)
- C \(10 \Omega\)
- D \(13.33 \Omega\)
Answer & Solution
Correct Answer
(D) \(13.33 \Omega\)
Step-by-step Solution
Detailed explanation
The given circuit diagram is redrawn as Since, \[ \frac{R_{A C}}{R_{A D}}=\frac{R_{B C}}{R_{D B}} \] Given circuit is balanced Wheatstone bridge, hence \(30 \Omega\) resistance is useless. Therefore,…
