Question : 153 of 200

Marks: +1, -0

The impedance at resonance offered by a parallel resonant circuit is _____.

minimum given by 1/CR
minimum given by L/CR
maximum given by L/CR
maximum given by 1/CR

Solution:

Impedance of a parallel circuit at resonance is equivalent to the value of the resistance and this value must, therefore represent the maximum dynamic impedance (

Z_d

) of the circuit as shown.

Z_d =L/{RC}
