### Electronic component

**electronic componentscomponentscomponent**

An electrical network is an interconnection of electrical components (e.g., batteries, resistors, inductors, capacitors, switches, transistors) or a model of such an interconnection, consisting of electrical elements (e.g., voltage sources, current sources, resistances, inductances, capacitances).

These leads connect to other electrical components, often over wire, to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator).

### Capacitor

**capacitorscapacitivecondenser**

An electrical network is an interconnection of electrical components (e.g., batteries, resistors, inductors, capacitors, switches, transistors) or a model of such an interconnection, consisting of electrical elements (e.g., voltage sources, current sources, resistances, inductances, capacitances).

While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit.

### Resistor

**Resistor controlresistorsResistance**

An electrical network is an interconnection of electrical components (e.g., batteries, resistors, inductors, capacitors, switches, transistors) or a model of such an interconnection, consisting of electrical elements (e.g., voltage sources, current sources, resistances, inductances, capacitances).

Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment.

### Switch

In electrical engineering, a switch is an electrical component that can "make" or "break" an electrical circuit, interrupting the current or diverting it from one conductor to another.

### Electrical element

Electrical elements are conceptual abstractions representing idealized electrical components, such as resistors, capacitors, and inductors, used in the analysis of electrical networks.

### Network analysis (electrical circuits)

**circuit theorycircuit analysisnetwork analysis**

Analysis of resistive circuits is less complicated than analysis of circuits containing capacitors and inductors.

A resistive circuit is a circuit containing only resistors, ideal current sources, and ideal voltage sources.

This design philosophy is called the lumped-element model and networks so designed are called lumped-element circuits.

It is useful in electrical systems (including electronics), mechanical multibody systems, heat transfer, acoustics, etc.

### Superposition theorem

**superpositionsuperposedsuperposition theorem for electric circuits**

A network is linear if its signals obey the principle of superposition; otherwise it is non-linear.

The superposition theorem for electrical circuits states that for a linear system the response (voltage or current) in any branch of a bilateral linear circuit having more than one independent source equals the algebraic sum of the responses caused by each independent source acting alone, where all the other independent sources are replaced by their internal impedances.

Networks designed to this model are called distributed-element circuits.

Distributed-element circuits are electrical circuits composed of lengths of transmission lines or other distributed components.

### Distributed-element model

A new design model is needed for such cases called the distributed-element model.

In electrical engineering, the distributed-element model or transmission-line model of electrical circuits assumes that the attributes of the circuit (resistance, capacitance, and inductance) are distributed continuously throughout the material of the circuit.

### Inductance

**mutual inductanceinductivemutual induction**

If multiple electric circuits are located close to each other, the magnetic field of one can pass through the other; in this case the circuits are said to be inductively coupled.

### Dependent source

**controlled voltage/current sourcedependent generator**

Dependent sources depend upon a particular element of the circuit for delivering the power or voltage or current depending upon the type of source it is.

In the theory of electrical networks, a dependent source is a voltage source or a current source whose value depends on a voltage or current elsewhere in the network.

They are thus more easily analyzed, using powerful frequency domain methods such as Laplace transforms, to determine DC response, AC response, and transient response.

The DC solution of an electric circuit is the solution where all voltages and currents are constant.

* Voltage drop

Voltage drop is the decrease of electrical potential along the path of a current flowing in an electrical circuit.

In electrical engineering, ground or earth is the reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the earth.
