Coupling coefficient. The coupling coefficient is the ratio of the open-circuit actual voltage ratio to the ratio that would be obtained if all the flux coupled from one magnetic circuit to the other. The coupling coefficient is related to mutual inductance and self inductances in the following way. See more Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. The flow of electric current creates a magnetic field around the conductor. The field strength depends on the … See more A current $${\displaystyle i}$$ flowing through a conductor generates a magnetic field around the conductor, which is described by Ampere's circuital law. The total magnetic flux $${\displaystyle \Phi }$$ through a circuit is equal to the product of the perpendicular … See more In the most general case, inductance can be calculated from Maxwell's equations. Many important cases can be solved using simplifications. Where high frequency currents are considered, with skin effect, the surface current densities and magnetic field may be … See more • Electromagnetic induction • Gyrator • Hydraulic analogy • Leakage inductance See more The history of electromagnetic induction, a facet of electromagnetism, began with observations of the ancients: electric charge or static electricity (rubbing silk on amber), … See more If the current through a conductor with inductance is increasing, a voltage $${\displaystyle v(t)}$$ is induced across the conductor with a polarity that opposes the current—in … See more Mutual inductance is defined as the ratio between the EMF induced in one loop or coil by the rate of change of current in another loop or coil. Mutual inductance is given the symbol M. See more WebJul 3, 2024 · The piezoelectric charge coefficient is the ratio between the electric charge generated per unit area and an applied force and is expressed in Coulomb/Newton (C/N). The d constants are calculated from the equation: where: k: electro-mechanical coupling coefficient. K T: relative dielectric constant.
