Different voltage sources in parallel
That totaly depends on the internal resistors of the voltage sources.







simulate this circuit &ndash; Schematic created using CircuitLab

Then you can use the superposition principle and calculate the voltage level on the top of the circuit.



So, if both internal resistors have the same value the voltage V_out would be 7.5V. With other resistor values the voltage can vary between 5V and 10V.
