/diy/ - Do It Yourself

yeah, regarding the mosfet i also simulated something like this. it looks better but there are some other issues there, since now that inductor is in parallel with the load resistor and <something happens but i forgot but it only works well for very high inductances>. as for the resonant circuit, yeah that is a totally different approach, I did something like this, but I am not building a meter. I specifically need to be able to observe the charge/discharge waveforms for 1st order diff eq for RC and RL, and be able to measure the time constants looking at the waveform (63% of Vcc). Seems easy for capacitors but not for inductors. Inductors are just nasty creatures. To be able to measure R/L in the range of single mH and below requires high frequencies or R would have too be too low so it would draw too much current.
