Which term describes a technique used to ignite fireworks using electrical current?

The term "electrical ignition" accurately describes the technique of using electrical current to ignite fireworks. This method involves the use of a firing system that sends an electric signal to ignite a pyrotechnic device. Electrical ignition is often preferred for its precision and reliability, allowing for synchronized displays and the ability to control ignition timing from a safe distance. This enhances both safety and show quality, as it minimizes the risks associated with manual ignition.

Manual ignition, on the other hand, involves physically igniting fireworks by hand, which poses greater risks due to proximity to the explosives. Ignition by fusee refers to the use of a fuse that burns slowly to ignite the fireworks, while instant ignition suggests a not-commonly used technique that implies immediate firing without delays, which is not as specifically defined as electrical ignition. Thus, the context and application of electrical ignition in enhancing safety and control during fireworks shows make it the most appropriate choice.
