The series and parallel resonance on L-C circuit' differs in that

Series resonance needs a high-resistance source for sharp increase in current
Parallel resonance needs a low-resistance source for a sharp increase in impedance
Series resistance needs a low-resistance source for sharp rise in current
Parallel resonance needs a low-resistance source for a sharp rise in line current
