Electret microphone
lede needed some elaboration on "eliminates the need for a polarizing power supply". Also needed to introduce the historical term "condenser" for capacitor, so later use of "condenser microphone" makes sense. Separate heading for "Electret material" pointing to main article.Tag: Visual edit

→2019 redefinition: change tense "will still freeze" to "still normally freezes" because the redefinition has happened, and insert "normally" qualifier because assumes normal conditions like 1 standard atmosphere.Tag: Visual edit

Kelvin
→2019 redefinition: replaced SI diagram with an modified copy that has the kelvin's dependencies blackened, so reader can better trace dependencies to kelvin. Moved the discussion on how ultimately depends on these constants to the caption of the diagram, to help reader better follow along with the diagram (though this does make caption longer, it is easier to follow). Added kelvin's exact value in terms of these universal constants.Tag: Visual edit

→2019 redefinition: Shorten wording to "allowing more accurate". Also sing semicolon for these two highly-related clauses. Also supposed to put a comma before "respectively" at end of sentence. The sentence "The challenge was to avoid degrading the accuracy of measurements close to the triple point" didn't belong with the paragraph on scientific & philosophical advantages, so moved earlier where it fits better.Tag: Visual edit

Kelvin
→Kelvin as a unit of noise temperature: A couple of technicalities. First I'm deleting "discrete" because it doesn't matter if the resistor is "discrete" or not, cause even if the resistor is integrated into an IC, it still produces the noise. Also the capacitors themselves don't produce any Johnson-Nyquist noise, but rather the noise that is talked about for the capacitors is more specifically a noise from the resistor in RC subcircuits, so I'm saying "associated kTC noise..."Tag: Visual edit

Avoiding word "Since" here because not exactly a direct consequence of kT being energy.Tags: Mobile editMobile web editAdvanced mobile edit
