Explain capacitance of bundled conductor line?
Capacitors are formed by placing two conductors near each other. Usually, they are plates separated by an insulating dielectric. The capacitance is a function of the area and closeness of the plates. Bundled conductors have capacitance for the same reason - they are conductors close to each other. Since capacitors work by transferring charge (remember that the equation of a capacitor is dv/dt = i/c) then a signal on one conductor can induce a "copy" of the signal on the other line - usually a faint copy, but a copy nontheless. This induced voltage effect is also known as interference, and must be considered in the final system design.
What is the formula for calculating self capacitance of an inductor when the value of capacitance and frequency for two capacitors is given?
You seem to be mixing up your terminology. There is no such thing as 'self-capacitance of an inductor'! If you know the frequency and equivalent capacitance for two capacitors, then you can find the equivalent capacitive reactance of the capacitors, but that's not what you seem to be asking! I suggest you rephrase the question.
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 the ability of two conducting surfaces to store voltage?
Capacitance
Why out put current increase in transformer with capacitance load?
ferranti effect...B.*If we use capacitive load the stator MMF aid the rotor MMF. It means that in times of capacitive load rotor flux and main field flux are additive. So the alternator voltage increase with capacitance loading.[By Akhtaruzzaman08]
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.
Is line to line fault a 3 phase fault?
'Line conductors' are the three 'hot' conductors (A-B-C) that connect a three-phase supply to a three-phase load. In some cases, a pair of line conductors (e.g. A-B, B-C, or C-A) is used to supply a single-phase load. A 'line fault' can be a short-circuit fault between all three, or any two, of these line conductors -whether they supply a three-phase load or a single-phase load.
Are the three conductors in a single phase 240v circuit considered to be in parallel?
If the three conductors are in a single cable they physically are positioned parallel in relationship to each other. True parallel conductors are combined to split the current. They have to be of equal length and size so that they split the load current between the two or three or four conductors. Conductors are paralleled so that multiple smaller conductors, which are easier to work with, can carry equally the total load current. To answer the question no, the three conductors in a 120/240 circuit are not considered to be in parallel. All three of these conductors could have a different current being carried by them depending on how the load is distributed.
How many wires are used for a 460 volt circuit breaker?
If the load is single phase and the load requires 460 volts to operate, then two conductors will be needed and they will connect to a two pole breaker. If the load is three phase and the load requires 460 volts to operate, then three conductors will be needed and they will connected to a three pole breaker. The sizing of the wires will depend upon the current that is drawn by the loads.

What is charging current in transmission lines?
Any two conductors separated by an insulating medium constitutes a condenser or capacitor.In case of overhead transmission lines, two conductors form the two plates of the capacitor and the air between the conductors behaves as dielectric medium. Thus an overhead transmission line can be assumed to have capacitance between the conductors throughout the length of the line. The capacitance is uniformly distributed over the length of the line and may be considered as uniform series of condensers connected between the conductors.When an alternating voltage is applied across the transmission line it draws the leading current even when supplying no load. This leading current will be in quadrature with the applied voltage and is termed as charging current. It must be noted that charging current is due to the capacitive effect between the conductors of the line and does not depend on the load. The strength of the charging currents depends on the voltage of transmission, the capacitance of the line and frequency of the ac supply. It is given by the expressionSignificance of Charging currents:Capacitance effect (responsible for charging currents) of the short transmission lines are negligible. However they are significant in medium and long distance transmission lines.In long distance transmission lines, during light loaded conditions receiving end voltage will be higher than sending end voltage. This is because of the charging currents and capacitive effect of the line
Does capacitance exist between two thin current-carrying conductors Explain?
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 stray capacitance and how is different from ordinary capacitor?
Any two adjacent conductors can be considered a capacitor, although the capacitance will be small unless the conductors are close together for long. This (often unwanted) effect is termed "stray capacitance". Stray capacitance can allow signals to leak between otherwise isolated circuits (an effect called crosstalk), and it can be a limiting factor for proper functioning of circuits at high frequency. Stray capacitance is often encountered in amplifier circuits in the form of "feedthrough" capacitance that interconnects the input and output nodes (both defined relative to a common ground). It is often convenient for analytical purposes to replace this capacitance with a combination of one input-to-ground capacitance and one output-to-ground capacitance. (The original configuration - including the input-to-output capacitance - is often referred to as a pi-configuration.) Miller's theorem can be used to effect this replacement. Miller's theorem states that, if the gain ratio of two nodes is 1/K, then an impedance of Z connecting the two nodes can be replaced with a Z/(1-k) impedance between the first node and ground and a KZ/(K-1) impedance between the second node and ground. (Since impedance varies inversely with capacitance, the internode capacitance, C, will be seen to have been replaced by a capacitance of KC from input to ground and a capacitance of (K-1)C/K from output to ground.) When the input-to-output gain is very large, the equivalent input-to-ground impedance is very small while the output-to-ground impedance is essentially equal to the original (input-to-output) impedance.
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.
