4.3: Combining Parallel Components
This would be impossible to achieve with each source trying to maintain a different voltage across the same two nodes. This may result in damage to the sources (e.g., exploding batteries). The main exception to this rule is if the sources have the same potential and the goal is to extend operational life (e.g., multiple D cell batteries in ...
circuit analysis
In practice, voltage sources (e.g. batteries or power supplies) have some limit of current that could flow (in or out), or a definite output impedance so that you don''t get two ''pure'' voltage sources in parallel; If they don''t get damaged, the voltage will be something between the two values, depending on the relative strengths of each.
