Part 2/4:
Connecting these electrodes is a wire, allowing for the flow of electrons, a critical aspect of how the cell operates.
Electron Movement and Current Flow
One of the striking observations during this process is the flow of electrons from the zinc plate into the external wire. The video illustrates this phenomenon through drops that fall into a tray on the left side, symbolizing the electrons released as zinc dissolves into the acid. Conversely, the right side of the tray represents the movement of electrons at the copper plate, where they are accepted after traveling through the wire.
