WebMay 3, 2024 · In an AC circuit, reactance is the opposition to current flow. A reactor, also known as a line reactor, is a coil wired in series between two points in a power system to minimize inrush current, voltage notching effects, and voltage spikes. Reactors may be tapped so that the voltage across them can be changed to compensate for a change in … Web1. The electric current passes through a metallic wire produces heat because of. 2.

WebChoke or coil is also used for RF filtering. The choke coil can be used only in ac circuits, not in dc circuits, because for dc(ω=0) the inductive reactance XL=ωL of the coil is zero, only the resistance of the coil remains effective which too is almost zero.
