WebElectrons start to flow, but as they do so the resistance to their flow (i.e. the resistance of the wire) generates a potential difference. The electron flow rate, i.e. the current, builds up until the potential difference is equal to the battery voltage, and at that point the current becomes constant. All this happens at about the speed of light. WebAn electron moving via the electric wires & loads of an external circuit experienced the resistance. The resistance is the hurdle to the flow of the charge. An electron does not move in a direct route between the terminals. It follows the zigzag pattern where the electron experiences several collisions with stable atoms in the conducting material. prographics screen printing

The electrons have to climb over the stool to move forward. The whole electron chain will slow down, showing that the current slows down when there is a resistance. The resistance of a given object depends primarily on two factors: what material it is made of, and its shape. For a given material, the resistance is inversely proportional to the cross-sectional area; for example, a thick copper wire has lower resistance than an otherwise-identical thin copper wire. Also, for a given material, the resistance is proportional to the length; for example, a long coppe…
