The opposition to current flow in an electrical circuit is called _____. resistance The law that defines the relationship between current, voltage and resistance is called _____ Law.
In an electrical circuit always current flows from-ve terminal of the source voltage to positive terminal in a closed circuit and such nature of flowing is called as conventi â¦ on current flow.  Conventional current flow, positive to negative.Electron flow negative to positive.See related link below.n an electrical circuit always current flows from-ve terminal of the source voltage to positive terminal in a closed circuit and such nature of flowing is called as conventi â¦ on current flow.
