Total Reactance Equation:
From: | To: |
Total reactance (Xtotal) is the difference between inductive reactance (XL) and capacitive reactance (XC) in an AC circuit. It represents the combined opposition to current flow caused by inductors and capacitors.
The calculator uses the total reactance equation:
Where:
Explanation: In AC circuits, inductors and capacitors create reactances that oppose current flow, with inductors opposing changes in current and capacitors opposing changes in voltage.
Details: Calculating total reactance is essential for analyzing AC circuits, determining impedance, and designing filters and resonant circuits.
Tips: Enter both reactance values in ohms (Ω). The result will show the net reactance, which can be positive (net inductive), negative (net capacitive), or zero (resonance).
Q1: What does a positive total reactance mean?
A: A positive value indicates the circuit is predominantly inductive (XL > XC).
Q2: What does a negative total reactance mean?
A: A negative value indicates the circuit is predominantly capacitive (XC > XL).
Q3: What happens when total reactance is zero?
A: When Xtotal = 0, the circuit is at resonance, with XL = XC.
Q4: How is reactance different from resistance?
A: Reactance depends on frequency and stores/releases energy, while resistance dissipates energy as heat and is frequency-independent.
Q5: How do I calculate XL and XC?
A: XL = 2πfL and XC = 1/(2πfC), where f is frequency, L is inductance, and C is capacitance.
