| Feb 1, 2017 at 7:41 | comment | added | clabacchio | @BenVoigt I think you miss the point of the question, which is how can a component limit the current of another. Russell has a point, but added a lot of detail which confuses the reader | |
| Feb 1, 2017 at 7:35 | comment | added | Ben Voigt | @clabacchio: "constant" does not mean (only) "same at every point", can also means "same at every time" and that clearly is not true when considering step response of a circuit with complex impedances or response to a time-varying forcing function (source). It can also mean "independent of load changes", for example in a "constant-current source". The specific phrase "constant at every point" means that the parameter in question (current) IS a function of location and nothing else. | |
| Mar 20, 2012 at 17:10 | comment | added | exscape | Yes, I'm a bit confused. @Russell, could you give an example for a series circuit where current is NOT equal through all elements? | |
| Mar 20, 2012 at 13:56 | comment | added | clabacchio | I disagree with the last paragraph: in a series circuit (one wire in - one wire out) the current will be the same at every point outside the components (treating them as black boxes). | |
