During series resonance, the net reactive component of the circuit current evaluates to _______________?
Show answer Hide answer
Answer: A. Zero
Explanation
At series resonance, the inductive reactance and capacitive reactance cancel each other out completely in the circuit. This exact cancellation results in a net reactive component value that evaluates strictly to zero ohms. The impedance of the series circuit becomes purely resistive because all reactive voltage drops neutralize each other. Resonance occurs in AC circuits when frequency causes inductive and capacitive reactances to become equal in magnitude. Mathematical analysis shows that reactance depends directly on frequency for inductors and inversely for capacitors. Series resonant circuits exhibit maximum current flow because total circuit impedance reaches its minimum possible value.
Inductive describes a circuit state where net reactance is positive due to dominant inductive elements. Capacitive describes a circuit state where net reactance is negative due to dominant capacitive elements. None of the above is incorrect because zero is the exact mathematical evaluation of the net reactive component.
