Dec 7, 2015 at 17:20 | comment | added | Alfred Centauri | @JonCuster, the ideal current source doesn't produce a voltage, it produces a current (charge flow) that is independent of the voltage across. Now, if the current produced results in different charge densities on the current source terminals, then there is an associated voltage across the current source. True, the voltage across is a result of the current produced and, in this sense, it might be said that the current source 'provided' the voltage compatible with the source current through the external circuit. | |
Dec 7, 2015 at 16:08 | comment | added | Jon Custer | @AlfredCentauri - perhaps it would be better put as the ideal current source must provide whatever voltage is necessary to source the desired current? In reality, it seems that current sources are the least 'ideal' part of any set up, but that is another story... | |

Dec 7, 2015 at 2:25 | comment | added | Alfred Centauri | @tmwilson26, that's not quite true. A current source produces a current when the voltage across its terminals is zero too. At least in the context of an ideal current source, the voltage across is entirely determined by the external circuit. | |
Dec 7, 2015 at 2:22 | comment | added | tmwilson26 | I don't understand what you mean exactly, a current source produces current by creating a potential difference (voltage) between the two terminals. | |
