- Equation for Impedance of Inductor
The phase angles in the equations for the impedance of capacitors and inductors indicate that the voltage across a capacitor lags the current through it by a phase of /, while the voltage across an inductor leads the current through it by /. The identical voltage and current amplitudes indicate that the magnitude of the impedance is equal to one.
A non-inductive resistor of 10Ω, a capacitor of 100uF, and an inductor of 0.15H are connected in series to a 240V, 50Hz supply. Calculate the inductive reactance, the capacitive reactance, the circuits complex impedance and the power factor. R = R = 10Ω.
The AC impedance of an inductor is called inductive reactance. It increases with increasing frequency. The unit of electric charge is the coulomb. Ordinary matter is made up of atoms which have positively charged nuclei and negatively charged electrons surrounding them.
The impedance of an inductor is Z L = iω L where ω is the angular frequency of the applied voltage and L is the inductance of the inductor. The impedance of a inductor is purely reactive.
13 kwi 2024 · Admittance, \ (Y\), is the reciprocal of impedance. These are similar to the relation between conductance and resistance, and are convenient for parallel circuit combinations. Example \ (\PageIndex {1}\) Determine the reactances of a 1 mH inductor and a 2 \ (\mu\)F capacitor to a sine wave of 2 kHz.
This formula calculates the inductance, L, based on the product of the number of turns, N, across the conductor and the linking magnetic flux, Φ, divided by the current, I, producing the flux, according to the formula, L= (NΦ)/I. In the next equation, we calculate the impedance of the inductor.
