resistance readout shouldn't go to zero #134

Closed jbphet closed 6 years ago

jbphet commented 6 years ago

I'm working on sonification of the sim, and one of the challenges is to map the huge range of resistance values to pitch values. It seems like perhaps the range to too large, since it causes the readout to go to zero, as shown in the screen shot below. Zero resistance is a real thing in superconductivity, but we are showing zero resistance in a normal, presumably room-temperature wire, which is physically incorrect.

Assigning to @ariel-phet to decide if we should do something about this. One solution would be to revise the range, another would be to show more digits (perhaps dynamically).

@jbphet the readout was updated to three decimal places. See https://www.colorado.edu/physics/phet/dev/html/resistance-in-a-wire/1.5.0-dev.1/phet/resistance-in-a-wire_en_phet.html

@jbphet maybe you are stale or maybe the commits were only in a branch, but the issue is here: https://github.com/phetsims/resistance-in-a-wire/issues/125

I'm using an older phet-io version. Glad to hear it's been resolved - closing.
