network theorems are nothing but the special cases of KCL and KVL .....applying these for each and every branch in a huge network of multiple branches would be a hideous task so by using network theorems this problem can be removed.
various network theorems are :-
1. mesh analysis
2.nodal analysis
3.thevenin and norton theorems
4.dual networks
5.source transformations
in general these theorems are used for solving any circuit consisting of 5-6 loops ,for much complicated networks there are methods based on graph thoery like cut-set method , tri-sec method etc. these methods are difficult when we apply these in simple network but they serve as a very powerfull tool when we apply these on extremely complicated networks

What are the two basic types of electric circuits?
There are many different types of circuits, but, in basic electricity, perhaps the two most common types of circuits are parallel and series.A parallel-connected circuit is one in which the current divides into two or more flows with at least one load on each flow, whereas a series circuit has only one flow that passes through two or more consecutive loads. The input voltage to a parallel-connected circuit stays constant - so every branch of the circuit gets the same voltage from the power supply - but there is a different current flowing in each branch dependant on the resistance of the loads in that branch. Overall, no current gets lost because any current entering a particular junction (leading to branches) is always equal to the current leaving that junction.In a series-connected circuit the input current stays constant and the voltage is divided amongst the loads which are connected like links in a chain: each load component (a light, a resistor, etc.) is connected "head to tail" to the next one in the series circuit.A more complete answerActually there are four types of circuit, not two. These are series circuits, parallel circuits, series-parallel circuits, and complex circuits.'Complex circuits' (which are not necessarily complicated) describe any circuit that is not series, parallel, or series-parallel - a Wheatstone Bridge is an example of a complex circuit.The techniques for solving series, parallel, and series-parallel circuits cannot be used for solving complex circuits. Instead, network theorems, such as Thevenin's and Norton's Theorems must be used.
What the different between PVC and SVC?
Virtual circuits are usually permanent virtual circuits (PVCs), which means that they are defined for frequent and consistent use by the network. They do not change unless the network manager changes the network. Some common carriers also permit the use of switched virtual circuits (SVCs) although this is not common. Changing PVCs is done using software, but common carriers usually charge each time a PVC is established or removed. The difference between a PVC-Permanent Virtual Circuit and SVC-Switched Virtual Circuit is that an SVC must be reestablished each time data is to be sent. After that the SVC disappears.
Can Norton's theorem be applied to network which contains non linear resistance?
yesAnswerNo it cannot, any more than Ohm's Law can be applied to circuits with non-linear elements.
Why do you use wire in a circuit?
Why do you use a pipe in a water supply network ? wire is the carrier of the current ( AMPERE ) which is necessary to run your electrical device whatever it is. Same as in water supply network , pipe is the carrier of the water
What isbilateral impedance?
Bilateral impedance refers to the electrical impedance of a two-port network that behaves identically regardless of the direction of the signal flow. This means that the input and output characteristics are the same when the ports are interchanged. It is often used in the analysis of circuits where the components exhibit symmetrical properties, allowing for simplified calculations and understanding of circuit behavior. Bilateral impedance is critical in applications such as telecommunications and audio systems, where signal integrity is essential.
What is network theorem?
Network theorem refers to a set of principles and mathematical techniques used to analyze electrical circuits and networks. Key theorems include Thevenin's and Norton's theorems, which simplify complex circuits into equivalent circuits with voltage or current sources and resistances. These theorems facilitate easier calculations of circuit behavior, making it possible to determine voltage, current, and power distributions within a network. Overall, network theorems are essential tools for engineers and technicians in the design and analysis of electrical systems.
What is the advantage of using network reduction in electrical circuits?
It makes the calculation of currents and voltages easier.
How do you read electrical circuits?
Electrical circuit is a network that has closed path giving a return way for the current. It is a connection of power supply, conductors and loads.
What are the advantages of Norton's theorem?
It is used to reduce the complexitiy of the networkAnswerNorton's Theorem is one of several theorems necessary to solve 'complex' circuits -i.e. circuits that are not series, parallel, or series parallel.
Are simple circuit and complex circuit the two types of circuits?
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.
What is the purpose of an electrical tie breaker?
An electrical tie breaker is designed to protect electrical circuits from overloads and short circuits by interrupting the flow of electricity in case of faults. It ensures the safety of electrical systems and prevents potential damage to equipment and hazards such as fires. Additionally, tie breakers help maintain system stability by allowing the safe disconnection of parts of the network while maintaining power to other areas.
What is a Device that makes connections within a telephone network by opening and closing electrical circuits?
A device that makes connections within a telephone network by opening and closing electrical circuits is a switchboard. It enables communication by connecting different telephone lines together to establish a call between two parties. Switchboards were commonly used in early telephone systems before modern automated switching systems were developed.
What is an electrical network?
An electrical network is a system for supplying electricity in a given region.
What is an active electrical network?
The electrical network which has its own energy sources like current or voltage sources within the circuit is called as an active electrical network
What is the network of mutually coupled circuits?
This would be the inductance. It allows the circuits to work properly together when they are hooked up to it.

What are electrical circuits?
In general, electrical circuits refer to the pathways or routes that are used to deliver electric power onto the power grid and out to the site where a customer actually uses it. It's possible to say the electric power grid is a large electrical circuit. It is. We can use terms like wire or lines or conductors when we talk about the power grid. You already know that there are transformers, circuit breakers (disconnects), fuses and other "stuff" in the circuits. An electrical circuit could be any subsystem of the larger whole. The electrical circuits in a residential structure could be all the wiring from the meter and breaker panel to all locations in the home. The electrical circuits of your home can be described this way. An electrical circuit could be a subsystem of a piece of equipment that helps an observer differentiate it from another subsystem. In a TV, for example, the video circuits are electrical circuits that are separate from the audio circuits. Each is a distince electrical circuit in this light, and someone like, say, a repair technician will be looking in the audio circuits to see why your TV has no sound rather than in the video section. The two electrical circuits are distinct in this light. We could go on, but this may cover the basics acceptably.
