the "end" button on my keyboard doesn't seem to do anythingThe End key on my computer puts the cursor to the end on the line. I use it quite a lot, and if I pressed it one day and found it had just closed the app I was in the middle of using I'd be a bit miffed.
"Skin effect" means that high-frequency components (like lightning impulses) only travel through a thin skin on the outside of the conductor.
- That is why lightning down-conductors are made of a braid of many fine wires (with a large surface area) instead of one big conductor.
"Lightning impulse" - I'll guess it's not genuine AC with Voltage swings from +V to -V many times. I'll assume it's a single DC spike, from 0 (volts or amps) to +Vmax (or +Amax ) and back to 0 over a short time interval. I've never really looked at a Lightning strike and seen it as a plot of Voltage (or Current) vs. time, maybe it has mutiple sinusoidal components with different frequencies.
The proportion of the Tool was huge, in comparison to the job/product.See here:
It had a yellowish oily fluid in place of a milky white cutting fluid.
Anyways, i think the Thickness of the plates being cut is not allowing it to Curl.
ps - Why is it a $64,000 question?It's just a turn of phrase. It derives from an old 1960s TV contest in the USA where people answered questions with a prize that doubled each time. The final question was the $64,000 question.
I don't know where the ammeter is connected.Yes you do, follow the wiring:
So there is at least one path from plate to plate through the ammeter.No there isn't, the power supply has been disconnected, so the only connnection to the live plate is the insulated support on the stand, and the electroscope.
Is there any discernible pattern or explanation for the deflections shown on the ammeter during this part of the demonstration?Yes, as above, the knob is on the live side of the meter.
bends in the road can take the car in front out of the beam for a few seconds. So it appears to "remember" the speed of the car in front for perhaps 5 secondsBut the car in front could do an emergency stop in the 5 seconds it's out of view, can the assisted braking respond in the time left after the car reappears?
The more complexity in the control system, the more responsibility on the driver to understand it in detail, and to understand (and take action) when it hits corner cases where it doesn't do what you intend.The more complexity in the control system, the more opaque it generally gets.
if the car in front is slowing to turn a corner, and I can see that it will be safely out of the way before I get close; the radar system (configured for sensitive mode) sees the car in front slowing to a near stop in the line of sight, and rapidly slows down my car. Flicking off the speed control for a second resolves this problem.The problem with automation is fighting it to stop it doing what you don't want can often make more work than doing the job yourself.
