What is ground? Baby don't hurt me, don't hurt me, no more 🎶

Finally, the concept of "ground" makes sense with relation to electronic mechanisms that are functioning under circumstances where they cannot possibly be connected to the earth!!

I hand a hard time understanding ground until I watched your video . Thanks a lot, sir.

These circuit diagrams were helpful.  Never have seen such a clear explanation of ground.

Watched A LOT of videos and read a lot of articles about this. As a software engineer with an interest in hardware and circuits, the “common ground” in circuits has confused me for a very long time given my prior knowledge about earth ground i.e. the copper rods buried in homes in and buildings. This video cleared everything up.

You have a true gift of teaching and patience for extreme beginner. I am just beginning to understand how electricity works to fix up my riding mower (hopefully higher level things eventually) and all this is fascinating stuff.

Thank you. You have cleared up a lot of confusion over the term ground.

Fantastic video. You've been the only person to explain how to calculate the change in reference voltage. Voltage as a potential is easy enough to understand but when you have multiple sources of energy gets tricky but now I understand how another power source affects a reference voltage.

Thank you, professor!

thank you very much sir.

Thanks to professors like you sir and YouTube, the unlucky people who cannot afford having the right teaching can now have it. provided they understand English😊. Many thanks for your sharing 👍👍

Very interesting indeed.  Very well presented.  Thank you  Kim

This is such a great video. Thanks for such a wonderful explanation

Sir you are the best teacher

You're the man when it comes to circuit analysis

Great instruction, excellent simple teaching aids. Well done!!

Great explanation on grounds and demystifying the path of least resistance.

finally a worthy teacher

great lecture! thank you so much

very nice and informative. thank you so much.
