| The visible component of a coronal glow discharge occurs above the anode, often in layers. |
| The avalanching electrons move toward the anode, causing the applied voltage to collapse in picoseconds. |
| Current can only flow from the anode to the cathode, but not the other direction. |
| In chemistry the most common use of the term anode occurs in electrochemistry. |
| The third electrode may be biased at the potential of the anode through a ballast resistor, and be located near the cathode. |
| However, the sodium channel inactivation gates are open in the hyperpolarized virtual anode region, causing the tissue to be excitable. |
