What is an electrical circuit?

An electrical circuit is a set of interconnected electrical components that allow the flow of electric current. These components can include power sources, such as batteries or generators, and control elements, such as switches or relays.

Electrical current flows through the circuit due to the electrical potential difference between the components. The unit of measurement for electric current is the ampere (A), while the unit of measurement for electric potential is the volt (V).

In summary, electrical circuits are fundamental to the transmission and control of electrical power in a wide variety of devices and systems. The online electrical circuit simulations on this page will help you to improve the knowledge of electrical circuits. This is is essential for those working in fields related to electronics, electricity and energy.

Classification of electrical circuits

Electrical circuits can be classified according to various criteria that allow a better understanding of their operation and specific applications. The following are some of the most common classifications.

By configuration

Series electrical circuits

In series electrical circuits, components are connected one after the other, forming a single path for current flow.

Parallel electrical circuits

The components in a parallel electrical circuit are connected in separate branches. This allows current to flow through multiple paths.

Mixed electrical circuits

In mixed electrical circuits, series and parallel configurations are combined within a single circuit.

By functionality

Open electrical circuits

Open electrical circuits are those in which the flow of electric current is interrupted due to a disconnection or an open switch.

Closed electrical circuits

In closed electrical circuits, current flows without interruption because all connections are complete.

Short-circuited electrical circuits

In short-circuited electrical circuits, the electric current flows through a low-resistance path, usually due to an accidental connection, which can lead to damage from overheating.

By purpose

Power electrical circuits

Power electrical circuits are designed to transmit and distribute electrical energy in high-power applications, such as power grids.

Electronic electrical circuits

Electronic electrical circuits are used in electronic devices to process signals and control specific functions, such as in computers and cell phones.

Each of these classification criteria provides a unique perspective for analyzing and understanding electrical circuits, which is essential in the design, diagnosis and maintenance of electrical and electronic systems.

Electrical circuit simulations

The use of interactive simulations is a powerful tool for understanding these concepts by directly experiencing how circuits work in different configurations. These simulations allow parameters such as voltage, resistance and current intensity to be modified, providing a dynamic, hands-on educational experience.

Electrical Circuit Applications

In summary, electrical circuits are fundamental to the transmission and control of electrical power in a wide variety of devices and systems. Knowledge of electrical circuits is essential for those working in fields related to electronics, electricity and energy.
