Voltage is like water pressure. It pushes the amperage (water) through the wire (hose). If you connect a high voltage line to a low voltage line, the high voltage circuit will overcome the low voltage circuit and electricity will flow backwards through the low voltage circuit.
What are you trying to do and why would you connect these two lines together?

lets say i have 35A/5.5volts & 35mA/11kV
and then i connect both power lines together
