They are very effective in slowing down current surges or spikes and releasing the stored energy back into the circuit. Inductors, also known as coils, chokes or reactors, are characterised by inductance, which is the ratio of the voltage to the rate of change of current. They’re frequently used in radio equipment to block AC and allow DC.

Inductors are some of the fundamental components in electronics, and play a critical role in power systems, filtering, and isolation. Simply put, an inductor is a component that can store energy in the form of a magnetic field. A typical example of an inductor is a coil of wire which can be found in air coils, motors, and electromagnets.Angular Frequency ω= rad/s. Inductive reactance XL= Ω.

henry (H) named after the American Physicist Joseph Henry (1797-1878). One henry is the amount of inductance required to produce an e.m.f. of 1 volt in a conductor when the current in the conductor changes at the rate of 1 Ampere per second. The Henry is a rather large unit for use in electronics, with the milli-henry (mH) and micro-Z = [(Xc-XL)^2 + R]^0.5, where Z is the impedence, Xc is reactance of the capacitor which is equal to 1/(wC), w being the angular frequency and C being capacitance. XL is reactance of the coil which is equal to wL, L being the inductance of the coil, and R is resistance of the coil. Put R = 0 in case the coil has no resistance.Build your own—it’s easy!
