Question: 1 / 400

Which of the following is a common fuses used in explosive settings?

Candle

A candle is often used as a timing device in explosive settings because it provides a slow and controlled flame that can ignite an explosive charge after a specific period. The slow burn rate of a candle allows for delayed detonation, providing enough time for the person setting the device to vacate the area or for a coordinated explosion to occur.

In contrast, while items like cigarettes or firecrackers might seem related to the context of combustion or ignition, they do not serve the same practical purpose as a fuse in a controlled explosive setup. A cigarette burns relatively quickly and unevenly, making it unreliable as a timing device. Firecrackers are designed to explode on their own and are not intended to act as fuses for other explosives. Therefore, in terms of fuses used in explosive settings, a candle is the most appropriate choice.
