In radio tuners, they consist of a series of movable, interlocking metal vanes separated by gaps.
In radio tuners, they consist of a series of movable, interlocking metal vanes separated by gaps. In electrolytic types, an oxide film formed on the [*] plates by the action of a solid electrolyte acts as the dielectric. The simplest and earliest form was a Leyden jar. For 10 points—name these electrical components that provide reactance in AC circuits, by storing electric charge.
