Fine-tuning capacitor application circuit principle

Resonance and Tuning Methods

When a coil and capacitor are said to be tuned to resonance, the inductive and capacitive reactances are equal but opposite in action. When this condition is met, the reactances cancel one another. The tuned circuit then looks like a pure resis- tance at the frequency of resonance, a desirable condition.

6 FAQs about [Fine-tuning capacitor application circuit principle]

What is a tuning capacitor?

Tuning capacitors take a host of forms. Some are adjusted by means of screwdrivers or tuning tools. These are generally called trimmers or padders. They are set for resonance just once, then left in that posi- tion. Trimmer capacitors may be made with metal plates; insulation between the plates can be made of ceramic, plastic, mica or glass.

What are the different types of tuning capacitors?

Tuning capacitors come in several types, each with its own characteristics and applications: Variable Capacitors: These capacitors have adjustable capacitance achieved by changing the distance between their plates or altering the effective plate area. They are commonly used in tuning radio frequency circuits and oscillators.

What is a variable capacitor used for?

Can DC voltage be applied to a tuning capacitor?

In circuits where high RF power is developed, it is wise not to allow dc voltage to be applied to the tuning capacitor, even though some amateurs have done this in homemade gear. Fig. 7 shows both methods, but the illustration at B is recom- mended for safety reasons as well as voltage- breakdown considerations.

How does a variable capacitor adjust capacitance?

In order to adjust capacitance, a variable capacitor modifies the surface area of its overlapping plates. A variable capacitor, sometimes referred to as a tuning capacitor, is a kind of capacitor in which the capacitance can be mechanically or electrically altered on a regular basis.
