Would all the electrical items in the vehicle stop working due to the inability of electrons to travel in a forward motion?
As seen by a stationary observer - that is one who believes themselves to be stationary - nothing in the vehicle would move anywhere because it would appear frozen in time but --
Who is stationary and stationary in respect to what? The observer could be located on a distant planet, observing the speeding transit connect from a vast distance away. Taking the blatantly obvious propagation delay experienced by the observer due to the time taken from light emitted from afore mentioned transit diesel travelling at Cvel to arrive at the eyeball of the interstella observer. How could one safely conclude how valid any such observations were?
Hang on, am i observing or driving?
Am i to infer that your ascertation is that the faster you move, the slower you appear to move?
Although the flow of current in a moving vehicle does appear slower to a stationary observer, I'm fairly confident that the ammeter would read exactly the same.
Ah, but would this be related to the location of the ammeter?
If the ammeter were inside the transit, i might agree, but if the ammeter were mounted on a distant planet and utilising some un-feasibly long test leads (never going to be GS38 compliant, before you mention) how would the electrons move in that instance? Would the potential nuclear fusion occur at some point in the test leads?
The laws of electromagnetism would ensure this.
Law? at best, what we understand of our physical existence of all matter, you could only call it 'non-mandatory regulation'. 'Guidance' if you will. AFAIK, nobody or astral entity or deighty have so far been prosecuted for failure to comply with your 'law' of physics.
Here's a nice little thought experiment that's sometimes given to physics students:
Two electron beams are travelling parallel to each other. Each has an electrostatic field that repels the other. Each also has a magnetic field that attracts the other. Calculate the combined force.
You need to be more specific in your questioning. You describe that the electrons are travelling parallel to each other, however, you don't specify if they have identical speed, let alone velocity. Given the ambiguity, it could be the case that their vectors are parallel, yet opposite in direction.
One observer had a skin full of cheap cider at the S/U bar last night and can hardly even speel his name at the moment? (just a guess)
Is there any speed at which the two forces cancel exactly?
speed or velocity?
personally, i'd give that student a dry slap for trying to be a smart Rs.
Would the elctrons at the back of a cable, travelling forward crash into the electrons at the front of the cable
Electrons do have mass and so they tend to pile up at the back of an accelerating conductor. They don't get very far before electrostatic repulsion stops them but the effect is detectable.
So as i near the final stages of my overhaul of a vauxhall combo to allow it to cruise at warp factor 8, do you think it would be wise to progressively increase the CSA of electrical conductors toward the back of the van to allow for the 'bunching' of electrons due to atomic level inertia under acceleration at near light speed?
Before any pedants jump in here, warp speed isn't available whilst reversing - that would be silly.
It was once used in an attempt to measure the mass of the electron.
But they gave it up as they realised that this research would not enable them to increase fees payable by the average electrician and felt it a fruitless task.
I still say the neutral is the blue one.
I have too much time on my hands today
, i might go and see if theres any re-runs of Red Dwarf on Dave
