direct current
This term refers to a specific type of electrical flow where electrons move consistently in a single direction. It is most commonly associated with stored energy sources like batteries, fuel cells, and photovoltaic panels, contrasting with alternating current (AC) which reverses direction periodically.
In technical and engineering contexts, the term is frequently abbreviated as DC. Because it describes a specific physical phenomenon or a type of electricity, it is treated as an uncountable mass noun and does not have a plural form.
