Anode and cathode: In a galvanic cell

In a galvanic cell, where a spontaneous chemical reaction produces electricity, the anode is considered the positive electrode, and the cathode is considered the negative electrode. This is because the flow of electrons starts at the anode and ends at the cathode , creating a current from the anode to the cathode . Anode and cathode are electrodes in devices. When is the anode and when is the cathode ? Galvanic cell, battery, rechargeable battery, diode, electron tube. Anode vs. Cathode What's the Difference? Anode and cathode are two essential components in electrochemical cells. The anode is the electrode where oxidation occurs, meaning it loses electrons and becomes positively charged. On the other hand, the cathode is the electrode where reduction takes place, gaining electrons and becoming negatively charged. In simple terms, the anode is the source of electrons, while the cathode is the receiver. These two electrodes work together to create a flow of ...
