Be sure to keep the leads to the variable capacitors short and rigid.

We couldn't make a variable capacitor, it was impossible.

The original variable capacitors for which this kit was designed are in short supply now but we still have a few at £3.50 each.

Alternatively, a variable capacitor is used to tune the circuit.

Adjustments were then made to the variable capacitor in order to tune the circuit into a radio station.

Variable capacitors are considered of the highest quality when they have silver-plated plates.

Variable capacitors may have their capacitance changed by mechanical motion.

The combination of these printed circuit boards forms two variable capacitors.

For example, radio receivers rely on variable capacitors to tune the station frequency.

You use the variable capacitor to adjust what freq.

To control volume, the performer's other hand acts as the grounded plate of another variable capacitor.

The stability requirement also implies the variable capacitor may only tune a limited range of 1:1.025.

Ganging together a variable capacitor and inductor is not, however, a very practical solution.

Common control components used include potentiometers, variable capacitors, and rotary switches.

Intuitively, this can be understood as follows, for a variable capacitor based amplifier.

Mount the three variable capacitors with care.

The most simple form of the device is a variable capacitor with a coil wired across its terminals.

The variable capacitor tuned 0 - 300 pF but there is plenty of scope for experiment here.

Likewise, variable capacitors using air as a dielectric are vulnerable to vibrations moving the plates.

Differential variable capacitors can therefore be used in capacitive potentiometric circuits.

The two built-in trimmer capacitors inside each variable capacitor should be set to mid-value.

When compared to other variable capacitors, vacuum variables tend to be more precise and more stable.

An insect in contact with the plates is likely to cause a short circuit with the open frame design used on most air variable capacitors.

Their variable capacitor designs quickly became industry standards, and the component's schematic symbol was adopted as the company's logo.

The tracking can be done with a multi-section variable capacitor or some varactors driven by a common control voltage.
