The equivalent resistance between \(A\) and \(B\) as shown in figure is \(........\,k\Omega\)
- A \(5\)
- B \(30\)
- C \(10\)
- D \(20\)
Answer & Solution
Correct Answer
(A) \(5\)
Step-by-step Solution
Detailed explanation
\(V_A =V_D\) \(V_C =V_B\) All resistors are in parallel. So, \(\frac{1}{R_{e q 1}}=\frac{1}{10}+\frac{1}{20}+\frac{1}{20}\) \(R_{e q}=5\,k \Omega\)
