An alternating voltage of frequency ' ' is induced in electric circuit consisting of an inductance ' L ' and capacitance ' C ', connected in parallel. Then across the inductance coil

Options

  1. Acurrent is maximum when ^2= 1 LC
  2. Bcurrent is zero
  3. Cvoltage is minimum when ^2= 1 LC
  4. Dvoltage is maximum when ^2= 1 LC

Correct answer

D. voltage is maximum when ^2= 1 LC

Step-by-step solution

In a parallel LC circuit at ^2= 1 LC , the current is minimum. As current and voltage are out of phase by 90^ , the voltage would be maximum.
