WebMay 22, 2024 · You can measure the current by measuring the voltage over the current sense resitor using an oscilloscope. You start with a very low duty cycle to make sure the inductor is not saturating at the beginning of the measurement. Then you start increasing the durty cycle while watching the current slope on the oscilloscope. WebApr 13, 2024 · Inductors (Coils) The Q value is a parameter that indicates the quality of an inductor. "Q" stands for "Quality Factor". Coils easily pass direct current but act as a resistor to alternating current. This behavior is called inductive reactance. The higher the frequency of the alternating current, the higher the inductive reactance.
