Question

At a moment (t = 0) when charge on capacitor C1 is zero, the switch is closed. If I0 be the current through inductor at that instant, for t > 0,

  1. maximum current through inductor equals I subscript 0 end subscript divided by 2    
  2. maximum current through inductor equals fraction numerator C subscript 1 end subscript I subscript 0 end subscript over denominator C subscript 1 end subscript plus C subscript 2 end subscript end fraction    
  3. maximum charge on C subscript 1 end subscript equals fraction numerator C subscript 1 end subscript I subscript 0 end subscript square root of L C subscript 1 end subscript end root over denominator C subscript 1 end subscript plus C subscript 2 end subscript end fraction    
  4. maximum charge on C subscript 1 end subscript equals I subscript 0 end subscript C subscript 1 end subscript square root of fraction numerator L over denominator C subscript 1 end subscript plus C subscript 2 end subscript end fraction end root    

The correct answer is: maximum charge on C subscript 1 end subscript equals I subscript 0 end subscript C subscript 1 end subscript square root of fraction numerator L over denominator C subscript 1 end subscript plus C subscript 2 end subscript end fraction end root
