Contact UsWhat is the direction of the electricity flow in a DC circuit?
$begingroup$ There is a convention for the technical direction of the current: positive current flows from the plus pole of a battery to the minus pole by convention. The microscopic details of conduction in a specific medium/conductor are a different thing. In some conductors, like metals, it is actually electrons that flow.
Contact UsHow to Tell Positive and Negative Terminals on a Car Battery
Warning: Do not connect the negative (black) jumper cable to the negative battery terminal of the dead battery. Doing so can create sparks that ignite the hydrogen fumes from the battery. Double-check that the connections are secure. Start the vehicle with the good battery and bring engine speed up to around 1,500 – 2,000 RPMs.

Contact UsDo electrons actually flow when a voltage is applied?
You can now see that these electrons did not return to their source: they started at the negative pole and ended at the positive pole. We call this a closed path because there''s a circle: current starts at the battery and ends at the battery. There''s confusion because the battery actually exists of two objects: the positive and the negative pole.
