JEE Mains · Physics · STD 12 - 3. current electricity

The circuit shown here has two batteries of \(8.0\,V\) and \(16.0\,V\) and three resistors \(3\,\Omega ,\,9\,\Omega \) and \(9\,\Omega \) and a capacitor of \(5.0\,\mu F.\) How much is the current \(I\) in the circuit in steady state? ................... \(A\)

  1. A \(1.6\)
  2. B \(0.67\)
  3. C \(2.5\)
  4. D \(0.25\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(0.67\)

Step-by-step Solution

Detailed explanation

In steady state capacitor is fully charged hence no current will flow through line \(2\) . Bysimplyfing the circuit Hence resultant potential difference across resistances will be \(8.0 \,\mathrm{V}\) Thus current \(1=\frac{V}{R}=\frac{8.0}{3+9}=\frac{8}{12}\) or,…
