AC Inductance and Inductive Reactance
https://www.electronics-lab.com/article/ac-inductance-inductive-reactance/
Introduction In the previous tutorial concerning AC resistance, we have seen that the behavior of a resistor is the same in DC or AC regime under normal frequencies. However, other basic electrical components such the inductor, strongly depends on the frequency of the AC signal. A presentation of the concept of inductance is given in […]
Measure small LCs with a scope

Here is a simple way to measure an unknown inductance by forming a resonance LC circuit and measure it using an oscilloscope. Glen Chenier writes: One of our technicians recently asked for help determining the value of an SMT inductor. It was unmarked, and was many turns of very fine wire on a ferrite core. […]
