Anode and Cathode: Definition, Differences, Charges and

WebIn a galvanic (voltaic) cell, the anode is considered negative and the cathode is considered positive. This seems reasonable as the anode is the source of electrons and cathode is where the electrons flow. However, in an electrolytic cell, the anode is taken to be positive while the cathode is now negative. WebMay 17, 2024 · Current always enters a device though the anode, and leaves though the cathode, so it flows through the device from anode to cathode. That means that for a … WebJan 25, 2024 · The cathode of a galvanic cell is its positive terminal. In both galvanic and electrolytic cells, oxidation takes place at the anode and electrons flow from the anode to the cathode. Galvanic or Voltaic Cells The redox reaction in a galvanic cell is a spontaneous reaction. For this reason, galvanic cells are commonly used as batteries. smoothie bar business plan
