Does resistor has stray capacitance?
Yes, all electronic components have both stray capacitance and stray inductance.
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 is the reason of the frequency limitation in bridge?
A bridge has an upper frequency limit because above that frequency the measuement accuracy fails because of stray capacitance and inductance inside the bridge device.
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 cable distance using farads?
All underground cables have relatively high values of capacitance, due to the close proximity of their cores and earthed (grounded) metallic sheath. Manufacturers provide data for their cables, which express their capacitance in terms of capacitance per unit length, e.g. microfarads per metre.Certain categories of underground cable-fault can be located by measuring the capacitance (using an appropriate bridge circuit) of the healthy section of the cable then, having determined the capacitance per unit length for that type of cable, measuring-off the distance along the cable route to the fault position.
Does resistor has stray capacitance?
Yes, all electronic components have both stray capacitance and stray inductance.
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.
What is the stray capacitor?
Stray capacitance is undesired capacitance. Any electronic component (wires, resistors, etc.) has SOME capacitance; at high frequencies, this can become significant, becoming a problem for circuit design.
Effects of stray capacitance in ac fan out?
due to the load gates capacitance values,there is a increased load capacitance on the driving gate
What is the value of stray capacitance?
depends on circuit and its construction.
How does one reduce stray capacitance?
You can reduce stray capacitance by avoiding having long wires running parallel in circuits. Keep wires as short as possible. Long wires running along each other can exhibit stray capacitance effects. Another way is to cut long leads of components such as capacitors and inductors to make them as short as possible. If best, use SM components, as they have no leads which can cause this stray capacitance effect.
Does the stray capacitance or the resistance of the monitor cable have the greater effect on the monitor's color?
no

What is meant by stray capacitance?
ANSWER Stray capacitance is the capacitance in a circuit not caused by capacitor components. There is a small capacitive effect, often on the order of a few picofarads, between leads of ICs, traces on a PCB, wires in a cable, the power and ground planes in a PCB, etc. In high-speed circuits, stray capacitance can be enough to completely change the operation of a circuit -- even to the point of keeping it from working as designed. Note that capacitor "components" can include PCB traces specifically designed to act as capacitors.
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 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 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.
