The series and parallel resonance on L-C circuit' differs in that_________?
Correct answer: A. series resistance needs a low-resistance source for sharp rise in current
- A. series resistance needs a low-resistance source for sharp rise in current
- B. series resonance needs a high-resistance source for sharp increase in current
- C. parallel resonance needs a low-resistance source for a sharp in¬crease in impedance
- D. parallel resonance needs a low-resistance source for a sharp rise in line current
Explanation
At series resonance, a low source resistance allows the circuit current to rise sharply because the net reactance is zero. Parallel resonance instead produces a sharp impedance maximum under a suitably high-resistance source condition.
