An inductor coil always has a resistive component, although this is made as small as possible by designing the coil to have a high Q factor (Q factor is the ratio inductance/resistance). Therefore, Zv must consist of a variable resistance box and a variable inductance box. However, the ...
However, although the coil is a conductor, the wire winding has certain resistance components (R). The ratio between the resistance components and the frequency-dependent inductance (R/2πf L) is called the loss factor, and its inverse number is the Q value (Q=2πf L/R). Because f is...
For our purposes, it is sufficient to state that flux linkage Φ is equal to the magnetic field that exists in a coil multiplied by the number of turns of the coil. Inductance L is then defined as L = Φ/i (which is analogous to capacitance C = q/v), where i is the current in...

The single turn coil inductance can be utilized to calculate inductance of multiturn coil, L and is given by Eq. (2). L=N2L0L=N2L0E2 L=N2μ0rln(2rd)L=N2μ0rln2rdE3 where N is number of turns in a coil. This equation provides appropriate approximation for a cylindrical inductor, ...
A coil has a DC resistance of 100 Ω and an impedance of 180 Ω at a frequency of 0.5 kHz. What is the inductance of the coil in mH? Neglect the wiring capacitance of the coil at this frequency. Impedance of an RL Ci...
The magnetic field energy field energy stored in an inductor is u =(1)/(2) Li^2 thus, 32J = (1)/(2) L(4 A)^2 or, L = 4 H The power dissipated as heat is given by P = i^2 R or, 320 W = (4A)^2 R, giving R = 20 Omega The time constant of the
It is a well understood physical phenomenon that an electric current flowing through an inductor of inductance value L, which is measured in henrys (H), produces a magnetic fluxΦ as follows: Φ=LI Differentiating the preceding equation with respect to time gives the following circuit equation ...
