What is the magnitude of the circulating current within the components of a parallel LC circuit at resonance?

  1. It is at a minimum
  2. It is at a maximum
  3. It equals 1 divided by the quantity 2 times pi, multiplied by the square root of inductance L multiplied by capacitance C
  4. It equals 2 multiplied by pi, multiplied by frequency, multiplied by inductance
