Combination of Inductors, LR & LC Circuits

For the given circuit the current through battery of 6 V just after closing the switch 'S' will be _________ A.

Figure

Numerical answer type. Work it out, then open the answer.

Show answer and solution

Answer: 1

  1. Just after closing SS, the inductor opposes any sudden change, so its branch carries zero current (acts as an open circuit).
  2. Current then flows only through 2 Ω2\,\Omega and 4 Ω4\,\Omega in series with the battery.
  3. I=62+4=1 AI = \frac{6}{2 + 4} = 1\text{ A}
