In the case of the air variable capacitor, the maximum voltage rating is determined by the distance between the plates. Since the capacitance is inversely proportional to the distance between the plates, a compromise is required to achieve the desired capacitance and the required voltage rating.
One can limit the accuracy of a variable capacitor by understanding the physics of capacitors. A variable capacitor's error is typically proportional to the difference between its rated capacitance and physical size. Reducing the rated capacitance or making the object larger physically will lessen this.
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.
Adjustable capacitance makes these capacitors essential for fine-tuning electronic circuits. In electronic applications like radios and oscillators, their ability to adjust capacitance by changing surface area, plate spacing, or dielectric material allows for precise control.
The difference between the value of a variable capacitor as it is and the value that it should have based on a given table is its accuracy. One can limit the accuracy of a variable capacitor by understanding the physics of capacitors.
This means that a capacitor must be physically large to possess a large value of capacitance. Another important factor is the voltage rating of a capacitor. The dielectric strength limits the maximum voltage that can be applied to a material before it breaks down.
