The reason for it usually is due to the impedance of the meter you are using. It is also depends on what kind of circuit you are measuring. So what […]

Electrolytic capacitors can be found in many circuits in a circuit board but in today’s article I’m going to share with you about the electrolytic capacitors ESR found in the SMPS DC output line (filter circuit). I […]
