Thank you so much 😍

Thanks for the compliment about my videos. I have to keep the pace slow for the people who are being intorduced to these topics for the first time, as they need time to think about each point before moving on to the next one.

Thanks for the compliments.

Glad you liked my video. Thanks.

What is grounding? Grounding is an electrical engineering technique used to prevent people from receiving an electric shock from electrical equipment they use. The metal accessible parts of equipment are connected to a copper or other metal plate buried deep in the ground. While the phenomenon is one of involving the mutual repulsion of like charges, the manner of reducing the potential requires some knowledge of capacitance and that of the capacitance of single conductors. In the book "Fundamentals of electric theory and circuits", the principle of grounding is explained after descriptions of the neutrality of conductors, capacitance of a single conductor like the earth, sharing of charges by capacitors connected in parallel and leading to the theory and practice of grounding. P.S. A circuit zero or ground is used as a reference point for measuring potential diffetences or voltage and is different from grounding and this is also described in the above textbook. Electrostatics and circuits belong to one science and not two, that of electricity and magnetism. To know how they are unified visit this link matterandinteractions.org/articles-talks/ and view the article 'A unified treatment of electrostatics and circuits. B. Sherwood and R. Chabay, unpublished. (1999)' pdf. For a live demonstration of surface charge and its effects in circuits visit kzfaq.info/get/bejne/i52Cf8pem5-VlYU.html For comprehensive descriptions beginning with the fundamentals of charge, electric field, surface charge, current, voltage, simple circuit, parallel circuit, capacitors and capacitive reactance, inductors, inductive reactance, induced fields and transmission line effects, antennas and wave propagation, the contents of the book, make a distinct unified approach to electrostatics and circuits lending precision and clarity to the topics which is not found in most text books, see "Electric and Magnetic Interactions" by Chabay and Sherwood www.matterandinteractions.org or Fundamentals of electric theory and circuits by Sridhar Chitta www.wileyindia.com/fundamentals-of-electric-theory-and-circuits.html The book by Sridhar Chitta comes alongwith a CD with animated power point presentations for all chapters and voltage regulator, RC phase shift oscillators and differential amplifiers included additionally.

and eugene by transistor I mean transistors as amplifiers, Derek from veritasium have already done one on transistor as a switch

+Karan Agarwal, I already discuss transistors, both as switches and as amplifiers, in my video titled "Logic Gates from Transistors." Though, I plan to go into much more detail about transistors in future videos. Thanks.

VERY good!!

If you have a switch open or close in the circuit, this will generate a step function, and step functions have high frequency components when represented as a combination of sine waves.

So will it be an array of different waves at varying frequencies and amplitudes, harmonics per se?

+Mr Fox, glad you liked my video, and the choice of music. :)

In cable there are several wires inside. There are e.g. live (phase voltage), neutral (return wire) and usually protective earth (earth ground) wires as seen on video. These three wires were wired onto the wall socket at 03:00. This example person in question standing upon more or less insulating floor structure should touch the live wire and the neutral wire (or protective earth wire) simultaneously. However, in some cases electrocution is possible while in contact between neutral and protective earth or earth ground wires (01:30).

@@jkinkamo , a person can be electrocutated only touching live wire and the floor.

+Andrew Karpinen, the reason for using gold is because gold is an excellent conductor. But, because gold is expensive, what is typically done is that it is just used as a thin coating on another metal. The shields reflect the incoming electromagnetic waves. The shape of the shield is typically not critical, but in high voltage applications, you typically want to avoid sharp corners, these can cause large electric fields. In reply to the question about relativity, no we can't neglect C, and we can't assume instantaneous information, as the though experiments will not work otherwise.

+Physics Videos by Eugene Khutoryansky Thank you for the answers to my Questions. Also the Dogs said Woof and Bark! When I told them you said Hi. LOL. ....And Yes we (All the Dogs and I) watched the new vid tonight together lol.😃

Anywhere stray charges can come from, even static electricity. I used to have this problem with products I made that had electrically isolated signal outputs. When fed into the customers differential input data acquisition equipment, it wouldn't always work because is would sometimes allow the common mode output voltage to violate the common mode input range of the measurement equipment. I had to tell them to connect a ground to their instrumentation so often that I finally gave up and started putting large value resistors (100k) between the signal output common and ground. This was enough to maintain isolation more or less, but still provided a path for charges to bleed off to keep the common mode voltage referenced near ground.

+Gottfried Leibniz, current will not pass through this connection, and we don't want it to. The purpose of the connection is just to bring the voltage of the Earth ground and the circuit ground to the same value. If they are not connected, the voltage difference between them can be anything.

He mentioned in the video, but you only want EXACTLY one connection to earth ground. If you have more than one, then current can flow in the loop and subject the system to EM interference - current can't flow to earth ground if there is only one wire/ conductor connecting two circuits. Connecting a wire, or "node" to another wire or "node" simple makes the two nodes into the same node.

Physics Videos by Eugene Khutoryansky So you mentioned that even with a single point ground you could still have issues with the voltage along the return being slightly different due to resistance in the wire. This is where you talk about the naïve approach of adding more Earth ground ties can make things worse by creating a ground loop. So, if we can’t add more Earth ground points, what is the solution for this?

@@SiegeX1 Earth and circuit grounds should not be connected to one another. The earth ground is only for the metal chassis enclosure and you (so you're not shocked just by touching the device), not for the actual enclosed circuit inside

@@EugeneKhutoryansky If you don't want current to flow through this connection then don't make any connection in the first place. Keep circuit and earth ground separate, problem solved ; )
