Do ‘grounding’ and ‘earthing’ mean the same?

AI Thread Summary
Grounding and earthing refer to the same concept, primarily distinguished by regional terminology. Grounding can also denote a reference point in a circuit that isn't necessarily connected to the earth. A practical demonstration in a lab highlighted the importance of understanding how grounding works in circuits. Students learned that any point in a circuit can be treated as ground, which can lead to misconceptions. The discussion illustrates the nuances of grounding in electrical contexts and the potential for confusion among learners.

do ‘grounding’ and ‘earthing’ point to a same thing? Is there any difference between them?
 
Engineering news on Phys.org
Yes they do mean the same thing.
 
The only difference is the longitude.
 
"Grounding" is also a reference point in a circuit that is not necessarily earth.

I was demonstrating a lab once where the students had to use a dual channel scope to measure two different points in the circuit and understand the effect of the grounded scope probe clips - the point being to teach tham that they could make any point arbitrarily ground.

One guy really didn't get it so we measured the resistance between the scope clip and the Earth pin on the plug to explain it to him. So he then got 2 single channel scopes and plugged them into different outlets. I think his next plan was to run one of them on an extention cord to another planet.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
