WebJun 22, 2024 · A commonly used language in electrochemistry is that of anode and cathode. Electrons flow from the anode (electron provider or electron source) to the cathode (electron receiver or electron sink). If the voltmeter has a positive reading, the black wire is on the anode and the red wire is on the cathode.
