    What is an Electric Circuit?

    An electric circuit is a closed path through which electric current can flow. It is made up of different components like resistors, capacitors, inductors, and switches that are connected together by conductive wires. The electric circuit has a power source, which could be a battery or an electrical outlet, and the components are connected in a way that allows current to flow through them.

    What is Electronic Circuits?

    An electronic circuit is a type of electric circuit that involves the use of electronic components, such as diodes, transistors, and integrated circuits. These components are used to control the flow of electric current in the circuit, and they can be used to perform various functions like amplification, switching, and oscillation.


    What is an Electrical Network?

    An electrical network refers to a combination of various electrical components, such as resistors, capacitors, inductors, voltage and current sources, and other elements that are connected in some way, whether in a simple or complex configuration. While the term "electric circuit" is also used, "electrical network" typically applies to more complex systems that are solved by network theorems.


    Complex Networks

    In a complex electrical network, the components and elements are arranged in a complex manner, and cannot be easily solved using simple laws like Ohm's Law or Kirchhoff's laws. To solve and analyze these types of networks, specific techniques such as network theorems are used. These techniques include Norton's theorem, Thevenin's theorem, superposition theorem, star-delta transformation, and supernode and supermesh circuit analysis

    The goal of an electrical network is to transmit and distribute electrical power from generating stations to end-users, such as homes, businesses, and other facilities. The network achieves this by combining transmission lines, transformers, substations, distribution lines, and other components that work together to deliver electricity to its intended destinations.


    Types of Electric Circuits

    There are several different types of electric circuits, each with its own unique characteristics. Let's explore some of the most common types of electric circuits.


    Open Circuit

    An open circuit is a type of circuit that is incomplete, meaning that the circuit is not closed, and there is no path for the electric current to flow. An open circuit can occur when a switch is turned off, or when a wire is disconnected from a component.


    Closed Circuit

    A closed circuit is a complete circuit, meaning that the circuit is closed, and there is a path for the electric current to flow. In a closed circuit, the electric current flows from the power source, through the components, and back to the power source.

    Short Circuit

    A short circuit is a type of circuit where there is a low-resistance path for the electric current to flow. This can occur when two wires or components are accidentally connected, or when a wire touches a conducting surface. A short circuit can be dangerous, as it can cause overheating, fires, or electrical shock.


    Series Circuit

    A series circuit is a type of circuit where the components are connected in a series, meaning that the electric current flows through each component in turn. In a series circuit, the total resistance is equal to the sum of the resistances of each component.

    Parallel Circuit

    A parallel circuit is a type of circuit where the components are connected in parallel, meaning that the electric current can flow through each component independently. In a parallel circuit, the total resistance is less than the resistance of the individual components.

    Series-Parallel Circuit

    A series-parallel circuit is a type of circuit that combines elements of both series and parallel circuits. In a series-parallel circuit, some components are connected in series, and some are connected in parallel.


    Star-Delta Circuit

    A star-delta circuit is a type of circuit that is commonly used in three-phase electrical systems. It is a combination of a star (Y) and delta Circuit’s Parameters, Constants, and Related Terms

    There are several parameters, constants, and terms related to electric circuits. These parameters include voltage, current, resistance, impedance, capacitance, inductance, reactance, and power. Voltage is the measure of the potential difference between two points in a circuit, while current is the measure of the flow of charge in a circuit. Resistance is the measure of how much a material opposes the flow of electric current. Impedance is similar to resistance but takes into account the effects of capacitance and inductance. Capacitance is the measure of a capacitor's ability to store an electric charge. Inductance is the measure of an inductor's ability to store energy in a magnetic field.

    Reactance is the measure of the opposition a capacitor or inductor provides to the flow of AC current. Power is the rate at which energy is transferred in an electric circuit. It is calculated as the product of voltage and current. The unit of power is the watt (W).


    Active Circuit

    An active circuit is a circuit that contains a source of energy, such as a battery or generator, that supplies power to the circuit. 

    Active Circuit


    Passive Circuit

    A passive circuit is a circuit that does not contain a source of energy. Instead, it relies on the energy stored in capacitors or inductors. An example of a passive circuit is an RC circuit.

    Linear & Nonlinear Circuits

    Circuits can be categorized as linear or nonlinear circuits. Linear circuits follow linear relationships between voltage, current, and resistance. Nonlinear circuits do not follow linear relationships between voltage, current, and resistance.


    Linear Circuit

    A linear circuit is a circuit in which the output is directly proportional to the input. The relationship between the input and output can be represented by a straight line on a graph. An example of a linear circuit is a voltage divider circuit.


    Nonlinear Circuit

    A nonlinear circuit is a circuit in which the output is not directly proportional to the input. The relationship between the input and output cannot be represented by a straight line on a graph. An example of a nonlinear circuit is a diode circuit.


    Unilateral & Bilateral Circuits

    Unilateral circuits are circuits that allow the flow of current in only one direction. Bilateral circuits allow the flow of current in both directions.


    Unilateral Circuits

    An example of a unilateral circuit is a diode circuit. The diode allows current to flow in only one direction.
