A 'complex circuit' is a category of electric circuit that encompasses any circuit that is not just a series circuit, a parallel circuit, or a series-parallel circuit. An example of a complex circuit is a bridge circuit.
As you can see, such circuits are not necessarily complicated themselves; its just that they cannot be analyzed using only ohm's law and the power formula, but instead require more complicated methods like Theveninization, Kirchhoff's laws, etc. to be analyzed correctly.
that is called a perfect circuit
Complex frequency is utilized in electric circuits in order to simplify the math, essentially. It is very similar to the use of phasors, except complex frequency can cover all types of inputs, not just sinusoids.
Using superposition theorem.
no only series and parallelcircuitAnswerThere are four categories of circuit: series, parallel, series-parallel, and complex. 'Complex circuits' are not necessarily complicated (although they very often are); the term simply describes any circuit (e.g. bridge circuits) that doesn't fall into any of the first three categories and which need to be solved using network theorems.
One way is to use Thevenin's theory and methods. Léon Charles Thévenin was a French telegraph engineer who extended Ohm's Law to the analysis of complex electrical circuits.
Due to the complex nature of the system, Load Resistors will need to be fitted in both the indicator circuits and stop light circuits. Possibility of also requireing them in the park light circuits but not confirmed.
The circuit design process covers systems ranging from highly complex to simple. The design process for simple circuits can usually be completed by one person, while teams of designers may be required to complete the process for more complex circuits.
Use of complex numbers for circuit values (e.g. voltages, currents, reactances) is required to get correct answers for AC. The equations are the same as for DC circuits, but the numbers are complex not real. Also reactances vary with the frequency of the AC signals in the circuit.
There is one type of parallel circuit. An example of this type of circuit is the electrical wiring in a house. These circuits are generally very complex and have a single power source.
A television set is a complex group of circuits where we find components in series and others that are in parallel.
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.
