I am not speaking directly for FVGT, I am merely giving an answer on what I would think. 

Honestly, I would imagine that they know what a Taser is, so long as it still looks like a Taser Gun, whether it be pistol or Shotgun format. Electrical Magic is more of the harnessing raw electricity through technology like Tesla coils and Arc chambers, and batteries, and etc to wield electricity alone as a weapon. If anything a taser would most likely be considered an enchanted weapon, if it weren't simply understood as a Taser gun.
