ABSTRACT
Figure 29.2 |Y | plotted against frequency Since current I =V /Z =VY , the current is at aminimum value at resonance in a parallel network. From the ideal circuit of Figure 29.1 we have therefore established the following facts which apply to any parallel circuit. At resonance: (i) admittance Y is a minimum
be obtained by making the ‘imaginary’ part of the complex expression for admittance equal to zero.
