COMEDK · Physics · 23. Alternating Current

In the circuit shown, the internal resistance of the cell is negligible. The steady state current in the \(2 \Omega 2\) resistor is


  1. A \(0.9 \mathrm{~A}\)
  2. B \(1.5 \mathrm{~A}\)
  3. C \(0.6 \mathrm{~A}\)
  4. D \(1.2 \mathrm{~A}\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(0.9 \mathrm{~A}\)

Step-by-step Solution

Detailed explanation

In the steady state analysis capacitor acts as an open circuit. Therefore, the equivalent circuit is given as Thus, current in the \(4 \Omega\) resistor is zero. \(2 \Omega\) and \(3 \Omega\) resistors are parallel to each other. Thus, the resistance in the upper branch is given…
