In a parallel resonant circuit, the circuit current at resonance is maximum.
In parallel resonance current is minimum.
An RLC series circuit is underdamped. To make it overdamped, the value of R
For overdamping R is more.
Henry is equivalent to
Inductance is flux per ampere.
In a minimum function
If degrees of numerator and denominator were unequal, a pole or zero can be removed. Such a function cannot be a minimum function. Therefore degrees of numerator and denominator must be equal.
For a transmission line open circuit and short circuit impedances are 20 Ω and 5 Ω. Then characteristic impedance is
Z0 = (Zoc Zsc)1/2
