Q153 / 160 · TS EAMCET 2018 (04 May Shift 1) · Physics

In the circuit given below, the capacitor C is charged by closing the switch S1 and opening the switch S2. After charging, the switch S1 is opened and S2 is closed, then the maximum current in the circuit

Figure

  • A
    VLC
  • Correct answer
    B
    VCL
  • C
    V2πLC
  • D
    2πVLC

Solution

After capacitor getting charged fully S1 is open & S2 is closed.  

Hence capacitor will give its energy to an inductor. So as per energy conservation,

12CV2=12Li2

∴ i2=CV2L⇒i=VCL

Hence, the correct answer is option: 'B'.
