    I think that anyone here with even a little bit of knowledge of electrical theory can see that this guy just keeps super-confidently demonstrating how little he knows about it (and the English language). On the newsgroups they call someone like him who only posts stuff to intentionally get people annoyed a TROLL. I've often wondered why the moderators haven't done something about him already.

      Can you also imagine ordered?
      Do i need this digital toys?
      A simple analog ESR meter does too.
      It's like some kind of bad Haiku

        Well i only did it because i want to learn. If i really needed a meter i would have bought one. Besides, the reason progress has been slow is that uni is *very* crammed atm, there's lots of stuff to do, exams coming soon and so on.

            Simplest in the world ESR meter.

            Measuring signal-meander.

              So it not only uses the wrong frequency it's lowest measurement is 5 times what it is for for an 'oh so expensive' $70-$80 digital meter.

                Manufacturers state on their datasheets ESR is measured at 100 Khz it seems to be the standard.

                    100 or120Hz-this is already sclerosis
                    Reactance of the capacitance at a frequency of 50-100kHz is0.

                                          If the ESR capacitor will increase by 10 times,it is possible to measure the analog meter.
