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

At the time of the 5:57 video you say and write that Q is Q=tanδ while Q is Q=1/tanδ all congratulations on the video overall you have done a good job.

Nice video, and the narrator spoke with a very clear voice

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.

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.

Where can I find the document of this video?

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
