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 B. Sherwood and R. Chabay, unpublished.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 kzbin.info/www/bejne/i2i1fZpja55km7M 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.

this is a way of explaining why the grounded conductor (neutral) and grounding conductor (equipment ground) are bonded at only one point (service disconnect, or transformer disconnect). Small currents induced as "noise" into circuits can be nearly eliminated by installing an isolated ground, where the devices for sensitive equipment are not bonded to the adjacent metallic system, but run directly to the service ground.

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).

@MaxPowerElectric4 жыл бұрын
The third "ground" hole on a power outlet isn't just a connection to earth ground. It is a connection to the circuit ground, which is also connected to earth ground via a "grounding electrode." This is done to lower the total resistance between the electrical system and the earth, which helps to minimize potentially dangerous voltages from developing between the two due to high current flow from high energy sources (ie lightning). The reason for this third slot is to bond metal enclosures to the circuit ground (via the "equipment grounding conductor"), so in the event that an ungrounded or "hot/live" conductor (that is, relative to earth ground) makes contact with the enclosure, there will be a low resistance path back to the source (circuit ground) which will cause high current to flow and result in the overcurrent protection device (fuse or circuit breaker) opening and turning off the circuit. Without this low resistance path, current can still flow back to the source through the earth ground, possibly using a human body as part of this circuit. The resistance of this "ground fault" path may not be high enough to trigger the OCPD (say, 15A or 20A for a standard household circuit), but may still be low enough to pass lethal current through a person (~100mA).

1:31 the "earth ground" is obviously not part of the circuit. I don't understand how a current passes if we make a physical connection between "earth ground" and "circuit ground". how can we have a complete circuit then? and why can voltage between these two points be significantly different?
@EugeneKhutoryansky8 жыл бұрын
+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.
@Rebbyrag7 жыл бұрын
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.
@SiegeX16 жыл бұрын
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?

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.

The current loop consists of the live wire and return wire (or neutral). Generally speaking, the earth ground (or protective earth) wire provides less feasible path for the current. But the earth ground wire path is good enough for grounding dangerous static voltages. In this educational video the earth ground wire has more losses than the return wire or neutral. One can quite safely assume that in normal conditions the earth ground wire return path is "forbidden" for the cirsuit proper. In real life and especially in three phase systems the situation is somewhat different. I think I've seen a three phase video somewhere on this channel.

@@jkinkamo then you don't need to connect circuit and earth grounds together. People interact with the outer chassis only (which is connected to earth ground), not the isolated circuit inside! (not connected to anything except live and neutral wires)
