Trimmer Capacitors

A trimmer capacitor is a type of variable capacitor (a capacitor that can have its capacitance manually adjusted by changing the positioning of the two conductive plates). A trimmer capacitor differs from a regular variable capacitor in that it''s smaller, and its value is set initially during production and is meant to be left there for some time until an adjustment is needed.

What is a trimmer capacitor? How to use it?

Structure: The variable capacitor is composed of a set of fixed pieces and a group of moving pieces, and the rotation of the moving plate can continuously change the capacity of the capacitor. Trimmer capacitors are generally made of two or two sets of small metal shrapnel (with a medium in between), and the capacitance is adjusted by changing the

Very often, multiple stator/rotor sections are arranged behind one another on the same axis, allowing for several tuned circuits to be adjusted using the same control, e.g. a preselector, an input filter and the corresponding oscillator in a receiver circuit. The sections can have identical or different nominal capacitances, e.g. 2 × 330 pF for AM filter and oscillator, plus 3 × 45 pF for tw

What determines how much capacity the weapon capacitors have?

It''s not tied with weapons size. It''s tied with ship size. The bigger the ship, the bigger the capacitor which seems logic. Also, turrets have their own capacitor which are not tied to the main capacitor. And this is real unbalancing. You can''t go against a bigger ship by your own if
