im so dumb when it comes to electronics, i've been trying to understand impedance for a long time, finally i found a decent explanation, this channel looks promising
Couldn't find such a nice explanation of this concept anywhere else on Internet. Thanks.
Very well done. Simple, but actually explained, unlike in my text book.
It finally clicked. I now know the use of Norton and thevenin equivalent circuit design/schematics. It only took me studying MOSFETs to really try and understand it. Thanks Sir
Thank you Professor, your video clealy described the subject of impedence. I'm 72 and finally understand how to use this knowledge when using o'scopes and signal generators.
This was one of the best presentations I've seen. It squares up nicely to my university level Basic Electronics class.
Very simple and swift explanation exactly as promised in the title... Please keep it up!
Great educational video. Keep up the good work!
Great video, well done 🎉🎉
Thank you so much! Wonderful video!
Brilliant explanation.
Well done...
Please explain why the input impedance is not the total impedance of the circuit
Super ...
i wish some video explained the process of calculating it tho. im still confused as to when do you turn off sources, and reactive elements to calculate input and output impedance. and if thats the case, the how could ever an input or output impedance have complex numbers if the reactive elements arent on when making an analysis to calc impedence. also, is making the separate ac and dc analysis give different in out impedances? also same question for low and high frequencies, are there just like 8 different combinations of things happening on a single circuit just to get z_in and z_out?
Dear Sir, how can we findout (with mathamatics) I/P and O/P impedances in a two stage tube PRE AMPLIFIER (CASCADE wih and without -ve feed back).Please explain it with using equivalent circuits (Drawings) and Mathamatics.(Sorry for my bad english).I need step by step explanation. THANK YOU.
what is max power transfer? and efficiebcy
bruh im just trying to learn about headphones and i somehow got here
Seriously. I'm just trying to make my records sound better and I somehow end up on a video from the NUS Engineering Department.
lucky you are not a 3rd year engineering student who keeps forgetting the basics
*WHY HIGHER LOAD RESITANCE SPEAKERS CONSUME MORE POWER*---I have seen speakers with higher impedance like subwoofers are of high resistance value 8 ohms but normal speakers are of 4 ohms. But then why subwoofers are of higher wattage than 4 ohms speakers? When lower resistance load is connected to a power source, more current should pass.
Beginner I guess is a relative term.
