A cable can be as long as 1m for electricity into your PC or up to a 100 kilometres to carry electricity further or telecommunications data over a distance. With a copper cable a sender (or generator) sends the power or signal to the receiver (or load) which expects to receive it in the same shape, if a little attenuated.
Capacitance is one of the (primary) line constants which will attenuate frequencies and cause signal shapes to be recovered at the far end in a different shape.
The best example is a square wave pulse being sent, with the higher frequencies attenuated more than the lower ones - typical of shunt capacitance between 2 wires. Attenuating the higher frequencies will round off the pulses and make them more difficult to capture reliably at the far end.

What is the type of capacitance effect exhibited in P-N junction when it is reverse biased?
1. Transition capacitance 2. Diffusion capacitance 3. Space charge capacitance 4. Drift capacitance
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 pn junction capacitance?
The charge inside of a p-n diode with a connected voltage variety yields a capacitance is need to add circuit model of a p-n diode. The capacitance connected with the charge variety in the exhaustion layer is known as the intersection capacitance, in the same process capacitance connected with the abundance bearers in the semi impartial district is known as the dissemination capacitance.
When was Capacitance Electronic Disc created?
Capacitance Electronic Disc was created in 1981.
What is meant by transition and space charge capacitance of a diode?
space charge region in a diode or say a bjt for better understanding is same as the depletion region, both transition capacitance and depletion capacitance are the same c= (epsilon*A)/d ; where ... c is capacitance A is area and d is the depletion width the other type of capacitance is the diffusion capacitance c= (T*I)/(n*V) where ... c is the capacitance T is transition ti me I is the drift current n is emission coefficient ... its value is 1 for germanium and V is thermal voltage .. 26mv
What is the methods of improving string efficiency in transmission line?
capacitance grading method,static shielding
What are the different methods used for grading timber?
visual stress grading machine stress grading structural grading
Are junction capacitance and transition capacitance the same?
Junction capacitance is used to take the ripple out of DC circuits primarily. The other is used in voltage doublers or step ups as a storage.
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.
What refueling method is used when the capacitance values exceed corresponding maximum capacitance values?

How much capacitance is used in general circuit?
You need to be little more specific to get an accurate answer. Capacitance in which circuit? Thanks.
What statistics are used to calculate relative grading?
i need to know the exact formula used to calculate the relative grading thanks
What are VGA cables primarily used for?
VGA cables are cables which are used with computer electronics. The cables are primarily used to connect the monitor to the computer. Some of these cables are made for specific monitors or devices.
How does the Switching diode used in television tuning?
A: Those diodes are used as a variable capacitance whereby applying a voltage changes the capacitance which effect the frequency of the tuning circuit
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.
