self-capacitance

This is sometimes referred to as the "self-capacitance" of a body.

This way the self-capacitance of the main foil is crucially decreased.

This self-capacitance is an important consideration at high frequencies.

With self-capacitance, current senses the capacitive load of a finger on each column or row.

Large transformers (above 200 watts) begin to suffer from high frequency attenuation due to self-capacitance.

There are two types of PCT: mutual capacitance and self-capacitance.

Using this method, the self-capacitance of a conducting sphere of radius R is given by:

The inter-winding capacitance of a coil is sometimes called self-capacitance, but this is a different phenomenon.

Typical values of self-capacitance are:

Multi-layer windings are used to give high energy storage, as choke self-capacitance is not a prime consideration in this frequency range.

This unwanted capacitance is called "self-capacitance".

However, self-capacitance of a conductive object is a different phenomenon, referring to the capacitance of the object without reference to another object.

If the body is a conducting sphere, the self-capacitance is proportional to its radius, and is roughly 1pF per centimetre of radius.

Although apparently lacking a complete circuit, such a topology effectively obtains a return circuit by virtue of the load's self-capacitance and parasitic capacitance.

The turns of wire in proximity to each other have an equivalent self-capacitance that, when added to any cable capacitance present, resonates with the inductance of the winding.

It consists of two electrodes known as the drain and the source, connected through tunnel junctions to one common electrode with a low self-capacitance, known as the island.

The electrical connection of capacitance and inductance leads to a frequency where Electrical reactance of the self-inductance and self-capacitance in the balun are equal and opposite: resonance.

A similar process happens as electric charge builds up in one section of the antenna under the pressure of the signal voltage, and causes a local electric field around that section of antenna, due to the antenna's self-capacitance.

However, for an isolated conductor there also exists a property called self-capacitance, which is the amount of electric charge that must be added to an isolated conductor to raise its electric potential by one unit (i.e. one volt, in most measurement systems).

Although the self-capacitance of even large objects is rather small in ordinary terms, as Tesla himself appreciated it is possible to resonate that capacitance using a sufficiently large inductor (depending on the frequency used), in which case the large reactance of that capacitance is cancelled out.

It thus either passes a very low-powered current between forceps tips (bipolar output), or else passes an A.C. current between a single pointed metal electrode probe and the patient, with only the patient's self-capacitance providing a current sink (this is equivalent to considering displacement current to be the return current).
