suurus, mis tähistab elektrivoolu tihedust jagatuna voolusuunalise pinnaga
ISQ base quantity
scalar quantity equal to the flux of the electric current density through a given directed surface
scalar quantity equal to the quotient of the net quasi-infinitesimal electric charge dQ transferred through a surface during a quasi - infinitesimal time interval and the duration dt of that interval
Elektrivool on kiirus, millega elektrilaeng voolab vooluringis mööda konkreetsest punktist.
Good to know
Elektrivool läbi pinna on võrdne ajaintervalli jooksul läbi selle pinna läbinud elektrilaengu jagatise piiriga selle intervalli kestuse järgi, kui see kestus kipub olema null, ning pinnale jäävate laengukandjate puhul määratletakse elektrivool läbi selle pinna kõvera.
Electric current is the rate at which electric charge flows past a specific point in a circuit.
Good to know
The electric current through a surface is equal to the limit of the quotient of the electric charge transferred through that surface during a time interval by the duration of this interval when this duration tends to zero. For charge carriers confined to a surface, the electric current is defined through a curve of this surface (see the note to term “lineic electric current”).
