Complex Numbers: Complex numbers are such type of numbers which contain a real part and an imaginary part. Every real number can be a complex number but every complex number can’t be a real number complex no.’s r very important for the applications of quantum mechanics, electrical engineering, conformal mapping, method of steepest descent and for method of stationary phase etc. As we have to talk about only the importance of complex numbers in the electrical engineering so let us begin our discussion. Significance in Electrical Engineering: Before we start the discussion we should keep in mind that every real quantity can be expressed in terms of complex numbers easily, rather than explaining it in terms of real numbers.

We can describe the electric field strength and magnetic field strength by just one complex number. In Electromagnetism you often deal with sinusoidal waveforms. The link between sinusoidal and complex numbers is done by Euler's formula. We can write the sinusoidal as complex exponentials which helps a lot as they are then easily understandable. Complex number can also be used to measure the strength of an electromagnetic field as it is a directly measurable quantity. If the field will be all electric means that there will be no magnetic component then complex number will be purely real and it will be pure imaginary if there will be no electric component, only containing magnetic ones. And for cases like in which both are present then the complex number will consist of a non-zero real part and a non-zero imaginary part, basically they will have some value instead of being zero. If an attenuating medium is placed in the path of an electromagnetic wave than it can also be measured by using a complex number. The number will be purely real if the medium affects the magnitude of the wave but leaves the phase unchanged, and purely imaginary if the medium shifts the phase by 90 degrees. In general, a medium which scales the magnitude by a factor of R and shifts the phase by an angle t is described by the complex number as R*exp(
Stability of a complex in solution is known to be the separation of two compound resulting in equilibrium state, theoretically it was observed that; there greater association, the higher the stability of the
If more than one complex is formed at different pH values, their existence can be decided by this type of study. The pH, at which the absorption due to a particular complex species is far greater than that of metal ion and or the ligand alone, is selected for the study of that species. As the complex formation is the function of pH; it should be kept constant for particular system. Similarly, ionic strength is maintained constant throughout by adding an appropriate volume of sodium perchlorate. pH can be remained constant by using suitable buffer, provided the buffer does not interfere with the complex formation at wavelength where complex species show maximum
Cantor created M, where M is a real number that does not correspond with any natural number. Taking the first digit in the first real number, write down any other number for the tenth’s place of M. Then, take the second digit for the second real number and write down any other number for the hundredth’s place of M.
One job the requires algebra is an Animator. Animators have to draw all kinds of pictures and cartoons and it requires them to use linear algebra for every movement a character or object may make. Algebra also helps create special effects to make the images shine and sparkle. The requirements you must have to do this type of job is that of course you have to have talent, some type of degree in animation, and be pretty decent in math. Animators make around $47,000 a year.
Complex science provides an opportunity to break down something known to be a very large structure in order to see answers from a more individual point of view. It can become very beneficial in the long run depending on how it is applied. However, that’s just it you do not need to know how the entire global economic system works in order to benefit from it. When Benoit Mandelbrot created fractals they were used in various ways, to measure nature an...

Spectrum refers to the electromagnetic spectrum, which is the range of frequencies through which electromagnetic radiation travels. Electromagnetic radiation is the energy that travels at the speed of light in waves as a stream of photon particles. This form of energy encompasses radio waves, microwaves, visible, nonvisible light, X–rays and gamma rays, and these classifications are based upon the frequency at which the energy travels (see figure 1). In order to refer to a specific portion, also called a band, of the electromagnetic spectrum, one uses Hertz (Hz) as the unit of measurement.
In an electromagnetic wave, the constantly changing electric and magnetic fields affect each other so they both oscillate in different axis while the wave moves in a direction perpendicular to the oscillation of the fields as shown in Figure 1.
As an engineering student, design, develop and test electrical equipments is the major purpose of all time. In other words, electrical engineer is concerned with using electricity to transmit electric power. In electrical engineering, there are extensive subfields such as power engineering, control system and signal processing. It is also worth to point out the difference between electrical engineering and electronic engineering. According to the research, electronic engineering is a major that deal with the electronic system such as computers and radar, to be more specific, electronic engineers are concerned with using electricity to process information.
According to (Biesen) , In a complexometric titration a coordination covalent bond is formed via the ability of most metal ions to receive unshared pairs of electrons from a anion or molecule. Furthermore, a ligand: which is a molecule that contain a lone pair of electrons and can therefore form a bond with a complex ion or metal ion. Therefore a ligand determines the metal ion concentration. [2] Therefore according to (Hussain, 2007), the maximum amount of ligands that can take part in a titration are known as Werner’s Number and allow for complex formation.[13]
...ceptor. So this means that the interaction between the Lewis acid metal center in Nickel II perchlorate, Ni(ClO4)2 and the Bronsted base ammonia, NH3, will create a complex. Complex in here means it is a molecular existence formed by two or more element entities (ionic or neutral), or the correlated chemical type. In simpler words, it means that it is a substance that is composed by two or more substances each that can be able to exist independently.
Electric currents produce magnetic fields, they can be as small as macroscopic currents in wires, or microscopic currents in atomic orbits caused by electrons. The magnetic field B is described in terms of force on a moving charge in the Lorentz force law. The relationship of magnetic field and charges leads to many practical applications. Magnetic field sources are dipolar in nature, with a north and south magnetic pole. The magnetic field SI unit is the Tesla, it can be seen in the magnetic part of the Lorentz force law F magnetic = qvB composed of (Newton x second)/(Coulomb x meter). The smaller magnetic field unit is the
Electromagnetism is the branch of physics that studies the relationship between electricity and magnetism. Electromagnetism is based on the fact that (1) an electric current or a charging electric field produces a magnetic field or (2) a charging magnetic field produces an electric field.
Devlin believes that mathematics has four faces 1) Mathematics is a way to improve thinking as problem solving. 2) Mathematics is a way of knowing. 3) Mathematics is a way to improve creative medium. 4) Mathematics is applications. (Mann, 2005). Because mathematics has very important role in our life, teaching math in basic education is as important as any other subjects. Students should study math to help them how to solve problems and meet the practical needs such as collect, count, and process the data. Mathematics, moreover, is required students to be capable of following and understanding the future. It also helps students to be able to think creativity, logically, and critically (Happy & Listyani, 2011,
The abstractions can be anything from strings of numbers to geometric figures to sets of equations. In deriving, for instance, an expression for the change in the surface area of any regular solid as its volume approaches zero, mathematicians have no interest in any correspondence between geometric solids and physical objects in the real world. A central line of investigation in theoretical mathematics is identifying in each field of study a small set of basic ideas and rules from which all other interesting ideas and rules in that field can be logically deduced. Mathematicians are particularly pleased when previously unrelated parts of mathematics are found to be derivable from one another, or from some more general theory. Part of the sense of beauty that many people have perceived in mathematics lies not in finding the greatest richness or complexity but on the contrary, in finding the greatest economy and simplicity of representation and proof.
