The entire wire capacitance is applied to the gate output, and the delay through the wire itself is ignored. Elmore delay [5] is a simple approximation, often used where speed of calculation is important but the delay through the wire itself cannot be ignored. It uses the R and C values of the wire segments in a simple calculation.
Schematic representation of a circuit where a source is coupled to a load with a transmission line having characteristic impedance The characteristic impedance or surge impedance (usually written Z 0 ) of a uniform transmission line is the ratio of the amplitudes of voltage and current of a wave travelling in one direction along the line in the ...
To determine, for a given source, the voltage and the impedance , the value of the load impedance , for which this expression for the power yields a maximum, one first finds, for each fixed positive value of , the value of the reactive term for which the denominator: (+) + (+) is a minimum.
Increases in output load capacitance, often from placing increased fan-out loads on a wire, will also increase propagation delay. All of these factors influence each other through an RC time constant : any increase in load capacitance increases C, heat-induced resistance the R factor, and supply threshold voltage increases will affect whether ...
Some terminations on wiring devices designed only for copper wire would overheat under heavy current load and cause fires when used with aluminium conductors. Revised standards for wire materials and wiring devices (such as the CO/ALR "copper-aluminium-revised" designation) were developed to reduce these problems. While larger sizes are still ...
The output impedance is a measure of the source's propensity to drop in voltage when the load draws current, the source network being the portion of the network that transmits and the load network being the portion of the network that consumes. Because of this the output impedance is sometimes referred to as the source impedance or internal ...
Most top-load washing machines have a capacity of about 3 to 4 cubic feet and can handle up to 12 pounds of laundry. To determine load size when selecting a wash cycle, choose "medium" if the drum ...
Load affects the performance of circuits with respect to output voltages or currents, such as in sensors, voltage sources, and amplifiers. Mains power outlets provide an easy example: they supply power at constant voltage, with electrical appliances connected to the power circuit collectively making up the load.
