Inductor

An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. [1] An inductor typically consists of an insulated wire wound into a coil.. When the current flowing through the coil changes, the time-varying magnetic field induces an electromotive force (emf) in the conductor

In an inductor, the core provides the flux linkage path between the circuit winding and a non-magnetic gap, physically in series with the core. Virtually all of the energy is stored in the gap.

How much energy is stored in the inductor when a switch is opened?

An inductor stores energy when a current flows through it. The energy stored in the inductor is given by the formula: U = 1/2 L I2. When the switch is closed, this energy is stored in the inductor. However, when the switch is opened, this energy is dissipated in the resistor. An inductor doesn''t like change!!! When the switch is opened, the inductor will try to maintain the current that was flowing through it before the switch is opened.

What factors affect the energy storage capacity of an inductor?

The energy storage capacity of an inductor is influenced by several factors. Primarily, the inductance is directly proportional to the energy stored; a higher inductance means a greater capacity for energy storage. The current is equally significant, with the energy stored increasing with the square of the current.
