During flame rectification, in which direction is the current greater?

During flame rectification, the current generated is influenced by the flame's ionization effect, which occurs as the flame serves as a conductor between the electrode and the ground. The process relies on the principle that the flame creates ions that allow current to flow between the electrodes.

When determining the direction of the current, it is important to realize that the flame can be viewed as a bridge that facilitates the flow of current. The larger surface, typically the ground, plays a significant role in drawing the ions and completing the circuit. Consequently, the current flows more effectively towards the ground surface, where it can dissipate. This results in a greater current reading in that direction, emphasizing the essential relationship between the flame and the grounding mechanism in the system.

Understanding this concept is crucial in troubleshooting gas ignition systems, where proper current flow indicates that the flame is present and functioning correctly.
