That means CURRENT has to return back to the same battery where it's coming from. It cannot flow to the other group terminal of another battery even if it's if the same voltage.
10:09 i fail to understand why current will not flow id we just touch the hot wire and are grounded. I would assume that if we are coonected to ground there is a voltage difference between hot and ground and electricity should flow through us to ground as if that wrere a close circuit. But the explanation makes ir sound obvious that electricty canno flow unless the main circuit closes, closing with ground is not a viable option? But the video was so helpful. The final part of the parallel circuit where the path to ground is so low resistence that it saves the day was really good.
@Bob One thing is confusing though , you showed us that least resistant path is .001 Ohms but as you can see the electricity has too travel towards the source and ground is not copper wires, so you speak that there is back pressure when there is resistance.i mean .001ohms has the least resistance but after that it still need to flow and complete the circuit please explain it
@@inamaman9891 Good question. To me, it's almost like the Earth is acting like one giant capacitor that can absorb a lot of energy and still not be full. Or like a reservoir for current to flow into. Think of how lighting works, and you'll see a similar reaction to that of earth or chassis ground.
I love ur videos and they actually educated me and changed me for the better but just when I thought I had it figured out then this video confused me so bad because I thought voltage stayed the same I’m parallel circuits and if someone touched the metallic box then it seems that they would be in parallel and voltages the same on the person that touched it so I hope u explain somday
Many other videos from you are good but this one, i couldn't watch after several minutes. You repeat almost the same thing many times without getting to the point... or I didn't understand....and i quit after 7-8 minutes... intended as a constructive comment. I watch some of your other videos too which are good.
This video is very helpful to a lot of people to understand the grounding circuit concept and I am sure will save their levies. Thank you
Best explanation I found on RUclips!!!

I learnt so much Sir! thank you so much for these priceless, literally, videos.
You are a great teacher thanks
Nicely explained (as always). However, if grounding is considered adequate, why are GFCIs needed?
The best teacher by far....Great job bob.i am waiting for IT classes soon please
