Why do you replace voltage sources with short circuits and current sources with open circuits in thevenin's theorem?
The equivalent of an inactive Thevenin voltage source is a source with zero voltage between its terminals regardless of the current through it, best represented by a zero resistance, i.e. a short-circuit. The equivalent of an inactive Norton current source is a source through which no current can flow regardless of the voltage across it, best represented by an infinite resistance, i.e. an open circuit.

What sentence can I use for Electric Circuits?
Electric circuits can be described as closed loops that allow electric current to flow, enabling the operation of various electrical devices. They consist of components such as resistors, capacitors, and power sources, which work together to control and manage the flow of electricity. Understanding electric circuits is essential for designing and troubleshooting electrical systems.
What is different between dependent and independent dc source?
A dependent DC source is a circuit element whose output voltage or current depends on another voltage or current in the circuit, while an independent DC source provides a constant voltage or current regardless of other circuit elements. Independent sources can be either voltage sources or current sources, and they maintain their specified output without any influence from the circuit conditions. In contrast, dependent sources are typically used in controlled circuits and are represented by a specific relationship to another variable in the system.
What is a Thevenin's equivalent circuit consists of?
A Thevenin's equivalent circuit is a single voltage source in series with a single resistor. It is electrically the same as any combination of voltage sources, current sources, and resistors that, as a black box, has two terminals. The technique is useful in simplifying circuits, when analyzing them.

What are the names of the dutors in a circuit?
In a circuit, the primary types of sources (or "dutors") are voltage sources and current sources. Voltage sources provide a fixed voltage regardless of the current flowing through them, while current sources deliver a constant current regardless of the voltage across them. Both types can be ideal or real, with ideal sources having no internal resistance and real sources exhibiting some resistance.
How super position theorem solved?
The Superposition Theorem is used in linear circuit analysis to determine the contribution of each independent source to the overall circuit response. To apply it, you disable all but one independent source at a time: replace voltage sources with short circuits and current sources with open circuits. You then analyze the circuit to find the response (voltage or current) due to the active source. Finally, you sum all individual contributions to get the total response in the circuit.

Potentially, to replace current energy sources
When determining the thevenin equivalent circuit Resistance?
To determine the Thevenin equivalent resistance (Rth) of a circuit, first, you need to remove the load resistor from the circuit. Next, you can deactivate all independent sources: replace voltage sources with short circuits and current sources with open circuits. Finally, calculate the equivalent resistance seen from the terminals where the load was connected, which may involve combining resistances in series and parallel as necessary. This value represents the Thevenin resistance of the circuit.
What are continuous circuits?
Continuous circuits are electrical circuits that provide a continuous path for current to flow without interruption. They consist of interconnected components such as resistors, capacitors, and power sources, allowing for the steady movement of electric charge. In a continuous circuit, the flow of electricity is maintained as long as the circuit is closed and the power source is active. This contrasts with open circuits, where the flow of current is disrupted.
Which of these are not components of all circuits energy sources wires switches and loads?
Energy sources are not always present in circuits as some circuits rely on energy harvested from the environment.

What are three sources of power for control circuit?
Three sources of power for control circuits are batteries, power supplies, and solar panels. These sources provide the necessary voltage and current to operate control devices and components in a circuit.
What is different between dependent and independent dc source?

In contrast, dependent sources are typically used in controlled circuits and are represented by a specific relationship to another variable in the system.
What conclusion of Norton's theorem?
Norton's theorem states that any linear electrical network with voltage and current sources and resistances can be simplified to a single current source in parallel with a single resistor. This equivalent circuit, known as Norton's equivalent, allows for easier analysis of complex circuits by reducing them to a simpler form. The theorem is especially useful for analyzing circuits with multiple branches and helps in determining the current flowing through a specific component.
What is the use of superposition theorem?
superposition can find the voltage and current effect of each source to a particular branch of the circuit and we can calculate the total effect of the sources to know the effect of the total sources to that branch

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.
