Inter-turn capacitance refers to the capacitance that exists between adjacent turns of a coil or winding in an electrical component, such as a transformer or an inductor. This capacitance arises due to the proximity of the conductive turns, which can lead to unwanted capacitive coupling. It can affect the performance of high-frequency circuits by introducing additional reactive elements, potentially resulting in signal attenuation or distortion. Understanding inter-turn capacitance is important for optimizing the design of inductive components for specific applications.

What is capacitance ratio?
Capacitance ratio is a measure used to compare the capacitance of two different capacitors or capacitor systems. It is typically expressed as the ratio of the capacitance of one capacitor to that of another, indicating how much more or less capacitance one has relative to the other. This ratio is important in applications where matching capacitance values is critical for circuit performance and stability. A capacitance ratio greater than one indicates that the first capacitor has higher capacitance, while a ratio less than one indicates the opposite.
What is meant by transistion and space charge capacitance of a diode?
Diffusion capacitance is the capacitance due to transport of charge carriers between two terminals of a device. - Amog This diffusion capacitance is due to depletion capacitance which is a function of forward bias applied to emitter junction of a transistor and due to diffusion capacitance which a function of transconductance of the transistor. Its value is 100 pF. Tirupanyam B.V
What is pressure coil capacitance?
The series resistance (swamping resistance and multiplier) in pressure coil circuit has many turns.So in addition to inductance seen before, there are inter-turn capacitance also.If this capacitance effect exceeds the inductance effect, a phase-shift in pressure coil current will cause an error.When pressure coil capacitance roughly equals the inductance, the errors cancel each other.In most cases the inductance is more than the capacitance and thus the shunting capacitor mentioned before will serve the purpose.
Why ordinary diodes dont work properly At high frequencies?
Because of stray capacitance. At very high frequencies, the inter-electrode capacitance has a low enough impedance that the diode no longer cuts off when reverse-biased, there is still significant conduction via capacitive coupling. High-frequency diodes are constructed so as to minimize this capacitance.

What is the difference between self capacitance and mutual capacitance in the context of capacitive touch technology?
Self capacitance refers to the capacitance between the touch sensor and the ground, while mutual capacitance refers to the capacitance between two different touch sensors. In capacitive touch technology, self capacitance is used for single-touch detection, while mutual capacitance is used for multi-touch detection.

What is the difference between capacitance and stray capacitance?
Capacitance is an ability to store an electric charge. "If we consider two same conductors as capacitor,the capacitance will be small even the conductors are close together for long time." this effect is called Stray Capacitance.

Explain the use of a varactor diode in a parallel resonance circuit?
Short answer: By using a varactor diode as the capacitance in a parallel resonant ckt, by changing the reverse bias voltage you change the value of capacitance which in turn changes the resonant frequency. This makes a tuneable resonant ckt.
