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.
Yes, capacitance exists between two thin current-carrying conductors due to the electric field created by the charges on the conductors. The capacitance is defined as the ability of the conductors to store electrical energy when a voltage is applied between them. It is influenced by factors such as the distance between the conductors and their geometric shape.

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.
Why is capacitace inversely proportional to voltage?
Capacitance is not inversely proportional to voltage, rather capacitance is a measure of how much charge a capacitor can hold for a given voltage. The capacitance value remains constant regardless of the voltage applied across the capacitor. The relationship between capacitance, voltage, and charge is governed by the formula Q = CV, where Q is charge, C is capacitance, and V is voltage.
Why capacitance increase with a decrease in distance between plates?
Capacitance increases with a decrease in distance between plates because the electric field between the plates becomes stronger, storing more electric charge per unit voltage. This results in a higher capacitance value since the plates can hold more charge for the same applied voltage.
What happens to the capacitance fi the charge on the plates of a capacitor is doubled?
If the charge on the plates of a capacitor is doubled, the capacitance remains the same. Capacitance is determined by the physical dimensions and properties of the capacitor, such as the area of the plates, the distance between them, and the material between them.
Does charge on a parallel plate capacitor depend on distance between the plates?
No, the charge on a parallel plate capacitor does not depend on the distance between the plates. The charge stored in the capacitor is determined by the voltage applied across the plates and the capacitance of the capacitor. The distance between the plates affects the capacitance of the capacitor, but not the charge stored on it.
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.
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
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 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.
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?
What will the affect of capacitance of a capacitor when a conductor is placed between a capacitor?
capacitance will tend to zero
What is the relation between amperage and capacitance?
The relationship between amperage and capacitance is indirect. Capacitance stores and releases electrical energy, affecting the flow of current in a circuit. Higher capacitance can lead to slower changes in current (i.e., lower frequency), while lower capacitance can result in faster changes in current.
