I was new to this field and needed to understand impedance and measurement concepts and this video did the job well.

This is a great video and well done by Rohde Schwarz. I always remember the lead-lag properties by "ELI the ICE man". E (voltage) leads I (current) in L (inductors) and I (current) leads E (voltage) in C (capacitors).

I've been out of engineering school for many years now, but I still use ELI the ICE man when I think about impedance :)

High-quality pedagogy! Is it possible to measure the leakage current (pA to nA range) of a capacitor with your LCR meters? Thank you very much.

can anyone tell me the which $100-200+ - brand/model of hand held lcr meters has the best accuracy, mostly for capacitors and inductors with decent auto ranges? looking to buy a decent one, viewed a lot of vids, still can't determine if de 5000, extech, amprobe, klein, etc.. not looking for anything under $75, i've seen enough of those vids, they aren't worth spending any money on. i like the bk precision one but not for $400+, mostly used for electronics and appliances, maybe even higher inputs as in caps for hvac. i'd appreciate the input. thanks.

Hello sir can you guide me to measure the rlc lumped model of the simple copper wire of 2 to 3 cm using LCR meter. Or else how it can be measured??

Really nice video. Can I measure the current vs voltage applied on the DUT at a desired frequency ( or DC) ? Can I get the graphical display of I - V? For example, I want to get the I - V curve of a diode in DC condition or at a desired frequency. Is it possible by Precision LCR meter? Please. Regards Thanks a
