Parallel resonance LC circuit

  1. Sep 1, 2009 #1
    "At resonance frequency, the circuit impedance is maximum. It is resistive and its value is given L/Cr..."
    The book doesn't explain how impedance equals L/Cr, so I'm confused here. How is it derived? (Can you please show all the steps?)
    Thanking in advance...
