What is the element law of a capacitor in frequency domain?
The element law of a capacitor in frequency domain is based on Ohm's Law, which is capacitance times voltage is equal to current. The higher frequency, the lower the capacitance and vice versa.
How do you calculate antenna element?
This question cannot be answered as it gives no reference to the calculation your looking for: Frequency, Range, load, etc.
What is inductive reactance-?
There is no such term as 'inductance reactance'; the correct term is 'inductive reactance'. This is the opposition to the flow of a.c. current, due to the inductance of the load, and the frequency of the supply, and is measured in ohms.Inductive reactance is directly proportional to both the supply frequency and the load's inductance.
What is baritt diode?
It is a barrier-injection transit-time, a high frequency - semi - structural element of micro-electronics, as the diode is one of the electronic components.
What is the difference between Log Periodic and Yagi Uda antennas?
The Yagi consists of one driven element, plus one or more shorter elements acting as directors placed in front of it, plus one or more longer elements acting as reflectors placed behind it. Technically, the driven element is cut and the feed system is matched for a specific frequency ... the farther from that frequency, the more the performance of the Yagi degrades.The Log Periodic array consists of a uniformly tapered array of many elements. The lengths of the elements and the spacing between them decrease by a constant ratio as you move down the array, and all of the elements are electrically connected to the feed line.The objective is an array that's very broad in frequency. The idea is that at any given frequency within the total range of the array, the element closest to a resonant length will radiate/receive best, those in front of it will function as directors, and those behind it will function as reflectors.
What is the acoustic impedenece of aluminum?
There is no acoustic impedance of an element. Size is important. The acoustic impedance Z is a frequency f dependent parameter and is very useful, for example, for describing the behaviour of musical wind instruments.
How does the number of lines in the emission spectrum for an element compare with the number of lines in the absorption spectrum?
An emission spectrum depend on electrons transition in the atom of a chemical element; and elements are different.Absorption spectrum is based on the different absorption pics of different molecules, depending on the frequency of radiation.Spectral methods are largely used in analytical chemistry.
What is Transfer-impedance?
transfer impedance is impedance we encounter when an electrical current passing through one element of the system makes a voltage difference in other element of same system. eg:shield in a coaxial cable
Why can the bright-line spectrum of an element be used to identify an element?
The wave lengths of lines of the spectrum are different for each chemical element.
Can an element can be identified by its spectrum.?
The wave lengths of the lines in the spectrum are different for each chemical element.
Can an element be identified by its spectrum.?
The wave lengths of the lines in the spectrum are different for each chemical element.
Is the spacing between the lines in the spectrum of an element constant or does it vary?
The spacing between the lines in the spectrum of an element are constant. This is called the emission spectrum of an element. Each element has a unique emission spectra that will be the same each time.
Is there a element called spectrum?
no
How is it possible to identify an element by looking at spectrum?
Each element has a unique adsorption and/or radiant spectrum. If you compare the spectrum you get with a list of known spectrums you can make a match.
What is transfer impedence?
transfer impedance is impedance we encounter when an electrical current passing through one element of the system makes a voltage difference in other element of same system. eg:shield in a coaxial cable
Is it true that each element has a unique set of lines on a spectrum?
Yes , every element has different line in the spectrum.
What causes the color when you burn an element?
A spectrum is what it is called when an element burns and produce light. The spectrum of an element is based on what orbit the electrons are in and what energy level the electrons are at.
