The conductors of the transmission line act as a parallel plate of the capacitor and the air is just like the dielectric medium between them.A capacitor is a device used to store electrical charge and electrical energy.

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 relationship between potential difference and capacitance in a capacitor?
The relationship between potential difference and capacitance in a capacitor is that the potential difference across a capacitor is directly proportional to its capacitance. This means that as the capacitance of a capacitor increases, the potential difference across it also increases, and vice versa.
What is the relationship between current and capacitance in an electrical circuit?
The relationship between current and capacitance in an electrical circuit is that capacitance affects the flow of current in the circuit. Capacitance is a measure of how much charge a capacitor can store, and it influences the rate at which current can flow through the circuit. A higher capacitance can result in a slower flow of current, while a lower capacitance allows for a faster flow of current.
What is stray capacitance and how is different from ordinary capacitor?
Stray capacitance refers to unintended capacitance that exists in a circuit due to the proximity of components and wiring. It can affect the performance of a circuit by causing signal distortions or interference. In contrast, an ordinary capacitor is a discrete component intentionally added to a circuit to store and release electrical energy.
What is the relationship between capacitance and current in an electrical circuit?
The relationship between capacitance and current in an electrical circuit is that capacitance affects the flow of current in the circuit. A higher capacitance means the circuit can store more charge, which can impact the current flowing through the circuit. The current in a circuit with capacitance can change over time as the capacitor charges and discharges.
Does capacitance exists between two current carrying conductors?
Capacitance exists between any two conductors, current carrying or not.
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.
Difference between stray and parasitic capacitance?
Parasitic capacitance is unavoidable and usually unwanted capacity between two or more conductors which exists due to close proximity and which typically causes non-ideal circuit behavior. Stray capacitance, as it is typically thought of, is a type of parasitic capacitance. It is the capacity from a conductor to its surroundings which is the aggregate of the conductors in its environment inversely weighted by the distance to each of the environmental conductors.
What is the difference between capacitive reactance and capacitance?
Capacitance is a physical characteristic of a pair of conductors, dependent upon the distance between them, the opposing cross-sectional areas of those conductors, and the nature of the dielectric between them, and is measured in farads.Capacitive reactance is the opposition to the flow of current of a circuit, determined by that circuit's capacitance and the frequency of the a.c. supply applied to that circuit, and is measured in ohms.
How capacitance effects are taken into account in transmission lines?
Natural capacitance exists between conductors at different potentials, including between those conductors and earth (ground). The value of such capacitance is significantly higher with underground cables than with overhead lines, due to the close proximity of the individual conductors in an underground cable. Capacitance results in line losses in both a.c. overhead and underground systems, due to the corresponding capacitive reactance (opposition to a.c.). In the case of long, high-voltage, underground or under-sea cables, the capacitance losses can be so high that d.c. transmission is used instead of a.c. (d.c. eliminates capacitive line losses). In addition to the line losses, the electric fields resulting from the capacitance can lead to insulation breakdown -making it essential that 'sharp corners', etc., are avoided in their design and construction. One of the reasons that high-voltage overhead conductors are 'bundled' (i.e. more than one conductor per line) is to reduce the stress on individual line conductors that would otherwise occur due to their relatively small diameters.
The property of an electrical device that permits storage of electrically separated charges when potential differences exist between the conductors is called what?
The property is called capacitance. It is a measure of an electrical device's ability to store electrical charge, and it is dependent on the device's geometry and materials.
What is the effect of stray capacitance in a circuit?
stray capacitance(one that develops between wires ,conductors within the circuit) is obviously not useful as it alters the effective values of circuit components when developed in the oscillators and hence it destabilize the frequency of oscillations Engr.syed mudassir hussain
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 capacitance of two wires crossing?
That depends on the thickness of each wire, the angle at which they cross, the distance between them where they cross, and the nature of any material in the space between the conductors. Sadly, none of that information appears in the question.
Definition of a capacitance in mosfet?
Capacitance in mosfet is of three types: gate capacitance diffusion capacitance routing capacitance Gate capacitance: limits the speed of the device t which it can be operated Diffusion capacitance: It is the capacitance due to charge carriers between drain and source. Routing capacitance: It is the capacitance of the metal which is deposited on the top of oxide layer.
What will the affect of capacitance of a capacitor when a conductor is placed between a capacitor?
capacitance will tend to zero
How do you calculate the capacitance between insulators and conductors?
The voltage distribution across insulator strings is not equal, this because exist capacitances beteween insulators and tower and between insulators and conductor. So how i can calculate the stray capacitances across insulator strings?
