Does resistance of a rheostat affect current in the circuit?

a plot of V vs i gives a straight line, and the slope of this line is the wire's resistance. Here, why doesn't the resistance of the rheostat impact the experiment? I think you have this wrong. The ...

Why aren’t there any more revolutionary discoveries in science anymore?

In the field of biology, when you can image the atomic structure of protein molecules and then sequence them, you are done. A more powerful microscope will reveal nothing more to you. However, the ...

What are the disadvantages of using a single mode Fabry-Perot laser diodes in interferometry, as opposed to distributed feedback laser diodes?

I'm specifically interested in potential problems that FB laser diodes could cause when used in Michelson or Mach-Zehnder interferometers, due to a wider spectrum of FB lasers as oppsed to DFB lasers. ...

Photon pair generation

You seem to be referring to spontaneous parametric downconversion. It is not an easy experiment to do. You need a strong laser in the UV to get down-conversed photons at the red end of the visible ...

Examples of experiments replicating the idealized greenhouse model

What many refer to as the 'atmospheric greenhouse effect' is actually a conflation for the Kelvin-Helmholtz gravitationally-induced lapse rate. An actual greenhouse works primarily by blocking ...
