Calculator - Gain | Reactance | Resonance circuit

Capacitive Reactance is the opposition that a capacitor offers to the flow of alternating current (AC) in a circuit. It depends on the frequency of the AC signal and the capacitance of the capacitor.

Inductive Reactance iis the opposition that an inductor offers to the flow of AC in a circuit. It is directly proportional to the frequency of the AC signal and the inductance of the inductor.

Resonant frequency is where the inductive and capacitive reactances cancel, allowing the circuit to oscillate at maximum energy transfer.

Bandwidth is the range of frequencies between the upper and lower cutoff points where the circuit operates effectively.

Quality factor measures the sharpness of resonance, showing the balance of stored energy versus energy loss per cycle.

Cutoff frequencies mark the points where the output power drops to half its peak value, defining the bandwidth limits.
