The last one operates as an inductor of only one winding and its terminals are connected to a variable capacitor
of high voltage that allows the tuning of the antenna's resonance in a particular frequency.
Tuning capabilities that arise from the implementation of a variable capacitor
It consists of a fixed inductor and variable capacitor
. The non-contact measurement technology is used to obtain pressure information [7, 8].
The transmission-line segment ([[theta].sub.2]) and varactor ([C.sub.v1]) are equivalent to the serial-connected inductor (L) and variable capacitor
The RF power adjustment is accomplished by means of a semi-automatic circuit which controls the power supplied to the product, that is being dried through a variable capacitor
, located in the generator.
The materials generate static as they rub together while the circuitry acts like a variable capacitor
, storing up the electrical charge generated, reports New Scientist.
It has a stainless steel diaphragm and an insulated electrode, which forms a variable capacitor
. "As pressure increases or decreases, the capacitance changes," explained Duchesneau.

These firmly secured surfaces are mounted so that a minute change in applied pressure alters the gap between them, creating a variable capacitor
. The resulting change in capacitance is detected and converted to a proportional high-level analog signal.
