and the weapon firing, which generally decreases accuracy. However, in an electronic-firearm, an electric current instead of conventional mechanical action is used to ignite the propellant which fires the projectile. There are two approaches to electrically firing the cartridge. One method retains the primer, which functions analogously as a conventional primer. However, rather than being struck by a firing pin or by equivalent mechanical means, an

electric current An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume. The moving pa ...
