Coupled inductor formula
WebAn inductor is a two-terminal electrical component, used to store energy within a magnetic field once electric current supplies through it. It is also known as a choke, coil, or reactor. … 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. The inductance equations above are a consequence of Maxwell's equations. For the important case of electrical circuits consisting of thin wires, the derivation i…
