Class 4 SMD Coils

SMD coils or inductors, their function, how to measure them and everything there is to know about their behavior. Practically a coil is a thread of a conductive material that is wound that stores energy in the form of a magnetic field.
In mobile devices, or in cell phones, these SMD coils have very important functions when it comes to building the motherboard.
SMD Components Class number 4.
With this video we are going to answer all these questions:

How can a coil be measured?
What function does a coil have in a cell phone?
How does a coil or inductor work?
How is the impedance of a coil measured?
How does an inductor work?
What is an inductor and what is it for?
