The purpose of this question isn't to prove that you can touch a live wire without consequences, it's to help me understand the current flow between dissimilar grounds in a system. There is pretty much never a case where you should be safely touching a live wire. Why am I getting these...

I'm looking at an ungounded 3-phase system here for starters. In a perfectly ungrounded system, grabbing a phase seems safe in theory, but in practice (because perfect ungrounded doesn't exist), this is a bad idea. I'm trying to determine exactly WHY. If I have a perfect ungrounded system...

You didn't completely move to answer the second question, if you were intending to. I understand the potential measuring abilities, but if I have 2 LC's in phase with one another, let's say one hot is grounded instantaneously with a -60V. Now let's say that another LC's ground fault detection...

I work on a ship, and we have a 440V ungrounded distribution system. We have load centers that have transformers bumping that 440V down to 120V for recepticles and other services. This standard ship setup always has ground fault detection on the 440V side (at the switchboards) and at each...

okay well thanks for your response, but instead of saying yes or no, can you clarify why?

Excuse the simplified question title. I have very little knowledge in the world of organic chemistry, and chemistry alone. If I looked at the composition of banana (atomically), and then I got a little jar full of every element that is necessary to a banana's composition, could I make a...

You could also use a small magnet in the lid and use a reed switch in the box itself.

So I'm more into electricity, so fluids is not really a forte at all. But I have been thinking about this, and there must be some fundamental issue in the way that I view fluid pressure. Conditions: 1. I have a metal pipe, incompressible 2. There is water in the pipe, (incompressible? ...

I too can answer questions with metaphors that have absolutely no evidence... provide any?

I have a simple series circuit, with a 9V power supply, and a 1 ohm resistor. If I place to identical fuses in series on opposite sides of the resistor that are rated for <9A, which fuse will blow first? I am essentially asking if current flows identically through all points in a wire the...
