quote: ignoring air resistance...
Also ignoring distance from the earth (or moon or whatever)? The gravitational pull decreases as the item moves further away from a large mass, so the acceleration would be greatest just before hitting the ground (assuming no gas resistance, of course).
Toss a small dense object up a few feet. Ask where the point of maximum acceleration is. (while the object is in flight and ignoring air resistance).
Propose a small metal box with two terminals accessible. There is either a 5V voltage source with a 1 ohm resistor in series or a 5A current source with a 1 ohm resistor in parallel inside.
Can the candidate tell which it is?
I'm trying to remember some of the questions I was asked when I was interviewed. One involved two capacitors connected by a switch, with a charge on one of them. What happens when the switch is closed? I believe it was a resistanceless circuit. ;) It was kind of a theoretical question. Another, I believe, involved the gain of a a differential amplifier created with bipolar transistors. Another involved a D flip-flop. I believe there was a simple op-amp question. I remember in the interview mentioning to the interviewer something about a pot-core transformer from our student project, and then wishing I hadn't because it turned out he was a magnetics expert!
I'm not sure what other questions there were. Maybe there was a question regarding a resistor voltage divider.
Sorry, but you just described a high voltage power source. A standard ohmmeter would vaporize on contact! Lookup discussions of "Tethers in Space Handbook" (NASA & Smithsonian).
The first cable I designed for a vacuum chamber got laughed at (thought not meanly) because MY design called for standard Cadmium plated backshells on the connectors. How many engineers would know that in a vacuum, Cadmium evaporates, and then plates out on cooler surfaces. In this instance it would have been the cooled IR sensor we were to test.
Asking the history or makeup of certain terms might be going a bit far. I've never heard of where "ee" or "cc" comes from (at least I can't remember). And, even though I know pretty well how transistors work, I would have never remembered how the word "transistor" evolved.
@seaEE: Yes I Completely agree, having an understanding of why certain terms are used makes it clearer, and easier to remember, and actually puts a human story to the learning. The story of how the transistor got its name, for instance: "transistor" comes from "transconductance-varistor", refer here:
Re: VCC: I learned that the "cc" sub-script for positive supply rails meant "collector-collector" rather than "common-collector", for the same reason that negative rails had sub-script "ee" for "emitter-emitter" ie: just for emphasis... maybe others have different views about this..??
I ask, "What have you built at home recently?" -- most good engineers are always building something, even if it's not technical. Also, "What books have you read recently?" If they give you a blank look, it's a bad sign IMHO. Engineers seem to prefer hard SF.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
