Hot appliance due to jumpering receptacle neutral to ground screw

Please tell me if I have this right or not, relative to how the above-mentioned appliance becomes HOT.

Voltage feeds from the hot side of a receptacle to a plugged-in appliance, then back (when appliance is turned on) to the receptacle's neutral connection via the neutral side of the appliance cord. I know it's alternating current, etc., but bear with me, because this is how I visualize it.

If I understand correctly, if there were an open neutral, downstream of this receptacle (toward the panel), someone might connect/jumper the neutral wire at this receptacle to the receptacle's ground screw, in order to complete the circuit - albeit via the wrong "return" path, but it would, indeed, complete the circuit and run the appliance - yes?

Before I continue, I think I understand that a neutral wire can become HOT if there is an OPEN in this neutral wire... because the current is no longer flowing from the appliance in this neutral wire , so the voltage from the HOT wire no longer gets dropped across the appliance load, but remains at full line voltage all the way thru the appliance, when appliance is "On", and onto the neutral wire leaving the appliance, all the way up to the OPEN spot in this neutral. Thus a HOT neutral.

If that understanding is correct, then I think that condition relates to what results when the neutral at this appliance's receptacle is jumpered to the ground screw on the receptacle. The voltage can then reach the appliance housing via the ground prong on the appliance cord/plug. Voltage reaches the appliance housing, but goes nowhere else, so housing is energized at full line voltage, due to the partial, but incomplete parallel circuit the housing is now part of.... Result: HOT appliance. Correct?

How do I Delete a post? I'd contact Admin, but I'm still waiting to for a response to my first message as to why I don't get notification of Replies to subscribed threads (I checked my settings in UserCP). Maybe Admin is still trying to recover from vacation

Jumpering a neutral to the ground screw is dangerous and a serious code violation. It is clear from your post that you know nothing about electricity. Please stop whatever it is you're doing and call a professional.

You can't actually delete a thread or post. I can. What do you want deleted.

Post #69 of this thread: GFCI will not protect five outlets

I just remembered someone had told me previously I could use the exclamation mark (report post ) to ask for deletion of a post. I did that just now. Figured you would get it. Will that work in the future, or should I contact you directly?

I already sent it to trash.

Report post works best. All mods get an email of it.

md2lgyk, I'm afraid you've jumped (pretty far) to a conclusion that I'm actually trying to do something, as opposed to merely trying to understand something.

Ok, if my attempt (sixth post prior to this one - I did make a couple of edits/corrections in that post) at understanding how an appliance gets hot from 'jumpering a neutral to ground in a receptacle' is too wordy, could someone just tell me the path by which the voltage reaches the appliance to make it HOT. Receptacle ground screw to metal appliance housing (in the case of a corded/plugged in, three-pronged plug-type appliance)?
