    AC current measurement question

    It depends on the meter. Some have an internal shunt and can be connected directly (in series of course), some require an external shunt. If yours requires the latter, it will indeed fry without it. moo

    About how to prevent being struck by lightning

    Thanks for the link Alex4eva. :smile: The link I had for the homemade detector mentioned earlier is dead, but here's an image I had saved. The ferrite rode is inside a PVC pipe with end caps. moo

    Should Professors Focus on Teaching or Research? The Debate Explored

    Should Scientific Discussions Cater to the Lowest Common Denominator?

    Standards regarding what? Questions? Answers? Discussions? Interesting. There are threads about car engines, but the ones I have seen were regarding specifications and/or design, not repairs. Are you suggesting that no automotive topics should be allowed? Sorry for the quiz, but I'm new...

    Class III Laser Safety - Is There Any Danger?

    I think the determining factor here would be what type of surface the wall has. The more reflective it is, the greater the potential for eye damage. I'd use as non-reflective target as possible, such as a piece of black felt (or something similar) to focus the laser on. Berkeman makes a...

    Why is my rebound height not following the expected trendline?

    You're welcome. :wink: Btw, "wonky" is not a technical term... :biggrin: moo __________________ moo (moo') adj. Of no practical importance; irrelevant, such as a moo point (i.e. a cow's opinion).

    Why is my rebound height not following the expected trendline?

    When the ball impacts, the heavy side doesn't "stop" when the lighter side does, so the ball pivots a bit, and this continued movement by the heavier side translates into rotation. If the ball is dropped from a good height then surface aerodynamics will also come into play, but I doubt it's a...

    Why is my rebound height not following the expected trendline?

    I think your observations are correct. :wink: Unbalanced balls have an extremely "wonky" bounce. The lopsided impact causes rotation which absorbs much of the energy normally used in the rebound, plus the spin gives it a partially horizontal bounce rather than all vertical (which trades some...

    Should Scientific Discussions Cater to the Lowest Common Denominator?

    By now some folks are no doubt imagining worse things than you want to complain about anyway. Since you've already brought it up though, I'd say go ahead. :wink: moo __________________ moo (moo') adj. Of no practical importance; irrelevant, such as a moo point (i.e. a cow's opinion).

    About how to prevent being struck by lightning

    Lightning often strikes repeatedly in higher locations (hills, mountains) and tall objects such as towers and trees (although a tree may not be good for many hits). Like any short circuit, it constantly seeks the nearest discharge path. Detecting lightning activity and pinpointing a strike's...
