આકૃતિમાં દર્શાવ્યા મુજબ \(A\) અને \(B\) વચ્ચેનો સમતુલ્ય અવરોધ \(.........\,k\Omega\) છે.

  1. A \(5\)
  2. B \(30\)
  3. C \(10\)
  4. D \(20\)
Verified Solution

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, \(\frac{1}{R_{e q 1}}=\frac{1}{10}+\frac{1}{20}+\frac{1}{20}\) \(R_{e q}=5\,k \Omega\)
