# Electrical

Electrical or Electric is a term that means relating to electricity i.e. the set of physical phenomena associated with the presence and flow of electric charge.

vCalc's Electrical folder contains equations that relate to electricity and electrical elements  such as resistors, capacitors, switches, transformers and electronics.
