Reactance in electronics
WebIn electrical engineering, admittance is a measure of how easily a circuit or device will allow a current to flow. It is defined as the reciprocal of impedance, analogous to how … WebIn a series RLC circuit there becomes a frequency point were the inductive reactance of the inductor becomes equal in value to the capacitive reactance of the capacitor. In other words, XL = XC. The point at which this occurs is called the Resonant Frequency point, ( ƒr ) of the circuit, and as we are analysing a series RLC circuit this ...

WebQ Factor = 1/ Power Factor=1/Cosθ= Z/R …. (Where Power Factor Cosθ = R/Z) If R is too small with respect to Reactance. Then Q factor = Z/R = ωL/R = 2πfL / R … (ωL/R = 2πf) Also, Q Factor may be defined as the ratio between stored energy and Energy dissipated per cycle in a Circuit. Q = 2π x (Stored Energy/ Power loss) WebImpedance and Admittance. Impedance is the general expression for opposition to current in alternating current circuits. Impedance may be pure resistance or pure reactance, but usually it is a combination of resistance and reactance. The symbol Z is used for impedance, which is expressed in ohms. Impedance takes the general phasor form.
