Imaginary numbers are a mathematical concept, first defined to handle the square root of negative numbers. At first, many mathematicians did not think very kindly of them, until Euler's formula in the 1700's, then later applications in electricity and wave analysis were recognized.Complex numbers are numbers on a plane, for which special which special operations are defined. Complex numbers have a real part, and an imaginary part.There are several practical applications; for example, electrical engineers use complex numbers for circuit calculations with AC. There are other applications, too; for example, in art (creating interesting patterns, called fractals - based on calculations with complex numbers). Quantum mechanics routinely uses complex numbers.The Wikipedia article on complex numbers gives a good overview.The Picomonster website has some cool animations which show complex and imaginary numbers 'in action', so to speak.
A complex number is any number that can be represented in the form of a+bi, the real numbers are a and b, the imaginary number is i. Complex numbers are used in scientific and engineering fields.
Real and Complex. Real numbers are your everyday numbers that most people are familiar with and Complex numbers are Real numbers mixed with imaginary numbers. Of course this is a VERY BROAD oversimplification, and the question is somewhat vague in that there are other "types" of numbers that are used, but I think this is the answer you are looking for.
They are frequently used in Engineering applications.
Both Thévenin's theorem and Norton's theorem are used to simplify circuits, for circuit analysis.
To solve complex circuit problems effectively and efficiently, strategies such as breaking down the circuit into smaller parts, using Kirchhoff's laws, applying Ohm's law, and utilizing circuit analysis techniques like nodal analysis and mesh analysis can be helpful. These strategies can help in systematically analyzing the circuit, identifying unknown values, and determining the correct answers by following a logical and structured approach.
In order to calculate the complex power of a circuit, the conjugate of current is used. The Vrms of the circuit is multiplied by the complex conjugate of the total circuit current.
The term, 'complex circuit', is misleading, as they are not necessarily (but often are) complicated. A 'complex circuit' is simply a category used to describe any circuit that isn't a 'series', 'parallel', or 'series-parallel' circuit. This usually means that special theorems (e.g. Kirchhoff's, Norton's, Thevenin's, etc.) must be used to solve complex circuits.
Physics (e.g., quantum mechanics, relativity, other subfields) makes use of imaginary numbers. "Complex analysis" (i.e., calculus that includes imaginary numbers) can also be used to evaluate difficult integrals and to perform other mathematical tricks. Engineering, especially Electrical Engineering makes use of complex and imaginary numbers to simplify analysis of some circuits and waveforms.

Series and parallelImproved AnswerThere are four categories of circuit: series, parallel, series-parallel, and complex. 'Complex' is a 'catch-all', used to describe circuits that are not series, parallel, or series-parallel. An example of a 'complex' circuit is a Wheatstone Bridge circuit.
It is mostly convention. However this produces conflicts with the conventional mathematics usage of i as the square root of -1 in complex numbers, so in electronics the convention is to use j as the square root of -1 instead when working with complex numbers in the analysis of AC circuits.
A complex number is any number that can be represented in the form of a+bi, the real numbers are a and b, the imaginary number is i. Complex numbers are used in scientific and engineering fields.
I suggest asking separate questions for complex numbers, and for matrices. Complex numbers are used in a variety of fields, one of them is electrical engineering. As soon as AC circuits are analyzed, it turns out that complex numbers are the natural way to do this.
Complex numbers are basically "numbers in two dimensions". You can extend them to more dimensions; one superset that is sometimes used is the quaternions, which are numbers in four dimensions.
Thermal analysis are used to prevent the electronics circuit being damaged, such as heat sinks are used to absorb the heat which is created by the components to protect the sensitive components
To solve difficult equivalent resistance problems effectively, you can use strategies such as simplifying the circuit by combining resistors in series or parallel, applying Ohm's Law to calculate individual resistor values, and using Kirchhoff's laws to analyze complex circuits. Additionally, using circuit analysis techniques like nodal analysis or mesh analysis can help in solving challenging problems efficiently.
