Which ignition source requires heat transfer from an electrical source to maintain until the adjacent fuel ignition temperature?

• A. Radiant Ignition
• B. Autoignition
• C. Electrical Ignition
• D. Chemical Ignition

Answer: (C)

Electrical ignition is defined by supplying heat from an electrical source and keeping that energy flowing until the fuel-air mixture reaches its ignition temperature. The electric element or spark must be active long enough to bring the adjacent fuel to ignition. This sets it apart from other ignition modes: radiant ignition relies on heat from a nearby flame or hot surface rather than continuous electrical heating; autoignition happens when the fuel self-ignites once its temperature reaches the ignition point without any external heat supply; chemical ignition occurs when heat is produced by chemical reactions in the mixture itself, not from an external heating source.
