What is the magnitude of the current at the input of a parallel RLC circuit at resonance?

  1. Minimumپاسخ درست
  2. Maximum
  3. R/L
  4. L/R

توضیح

The impedance of a parallel resonant circuit peaks at resonance because the inductive and capacitive branch currents cancel at the terminals. With maximum impedance across a given source voltage, the current into the circuit is at its minimum.
