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 . For the important case of electrical circuits consisting of thin wires, the derivation i. The energy ($U$) stored in an inductor can be calculated using the formula: $$U = frac {1} {2} L I^2$$, where $L$ is the inductance and $I$ is the current. Inductors resist changes in current due to their stored energy, which can lead to time delays in circuits when switching occurs. [pdf]

Switched-mode power supplies (SMPS) convert AC and DC supplies into the required regulated DC power to efficiently power devices like. .
An inductor can be used in a buck regulatorto function as an output current ripple filter and an energy conversion element. The dual functionality of the inductor can save the cost. .
An inductor in an electrical circuit can have undesirable consequences if no safety considerations are implemented. Some common hazards related to the energy stored in inductors are as follows: 1. When an inductive circuit is. .
Some AC/DC and DC/DC applications (motors, transformers, heaters, etc.) can cause high Inrush currents to flow in an electrical system. These currents are needed to produce charging effects and magnetic fields when. [pdf]
