Agreed, there's no such thing as an ideal current source, but assuming there is, how do you differentiate it then is my question.
12.
An ideal current source would provide no energy to a short circuit and approach infinite energy and voltage as the load resistance approaches infinity ( an open circuit ).
13.
A "'generator "'in electrical circuit theory is one of two ideal elements : an ideal voltage source, or an ideal current source.
14.
Since a Van de Graaff generator can supply the same small current at almost any level of electrical potential, it is an example of a nearly ideal current source.
15.
In circuit theory, an "'ideal current source "'is a circuit element where the current through it is independent of the voltage across it.
16.
If the current through an ideal current source can be specified independently of any other variable in a circuit, it is called an " independent " current source.
17.
In circuit analysis, a current source having finite internal resistance is modeled by placing the value of that resistance across an ideal current source ( the Norton equivalent circuit ).
18.
A Norton equivalent circuit of the combined original Norton source " and " the buffer is an ideal current source " I A " with infinite Norton resistance.
19.
That is, the combination of the real generator and the INIC will now behave like a composed ideal current source; its output current will be the same for any load Z _ L.
20.
The impedance Z retains its value and the new voltage source V has value equal to the ideal current source's value times the impedance, according to Ohm's Law V = I * Z.
