COMMENTUncategorizedThe difference is that a votalge source keeps the votalge constant but a current source keeps the current constant. So, a votalge source does not care about the current, its duty is to keep the votalge as required. The current passing through a votalge source can be negative, zero or positive, it may vary by time but the votalge is constant for sure. A current source is the dual. Voltage across a current source can be positive, zero or negative or it can vary by time but the current is fixed. Do not try to find a simple physical element which matches with a current source. For a votalge source, a battery is a perfect match but there is no such a element which matches current sources that perfect. Some elements behave like current sources in some operating point.
