Old Man Posted March 20, 2015 Report Share Posted March 20, 2015 Yes. Although there are good ones too, like the guy who twisted the wire around his finger and wasn't electrocuted...until he put his other hand down on the table. Quote Link to comment Share on other sites More sharing options...

Bazza Posted March 20, 2015 Report Share Posted March 20, 2015 Yes. Although there are good ones too, like the guy who twisted the wire around his finger and wasn't electrocuted...until he put his other hand down on the table. What a shocking experience.

Cancer Posted March 24, 2015 Report Share Posted March 24, 2015 ... and in the serendipitous evil department, asking students to work out the units explicitly for an electric field turns out to be insanely amusing because so many of them have forgotten what units electric field is supposed to have (and it doesn't occur to them to reason it out). So there are many lines of algebra involving units, starting with garbage and ending with unrecognizeably different garbage. It makes me laugh like Darth Sidious.

Cancer Posted March 24, 2015 Report Share Posted March 24, 2015 They would have gone there, if they had ever been exposed to ergs. Quote Link to comment Share on other sites More sharing options...

Pariah Posted March 24, 2015 Report Share Posted March 24, 2015 "I don't find it confusing ... do you? The units and abbreviations all make perfect sense: "I" stands for current, measured in amps; "C" stands for capacitance, measured in farads; "R" stands for resistance, measured in ohms; "E" stands for voltage, measured (oddly enough) in volts; and "L" stands for inductance, measured in henrys. And they will tell you, with a straight face, that electronics requires a logical mind." (Amdahl, K. There Are No Electrons: Electronics for Earthlings; Clearwater Publishing Company, Inc.: Broomfield, CO, 1991; p. 186.) Quote Link to comment Share on other sites More sharing options...
Cancer Posted March 24, 2015 Report Share Posted March 24, 2015 Heh. Did you ever have to use Gaussian units for electromagnetism? Where the unit of charge is 1 statC = 1 g^1/2 cm^3/2 s^−1 ? Quote Link to comment Share on other sites More sharing options...

Old Man Posted March 24, 2015 Report Share Posted March 24, 2015 And they will tell you, with a straight face, that electronics requires a logical mind." Don't forget that the electrons actually move backward with respect to the current. Quote Link to comment Share on other sites More sharing options...
