Circuit électronique
An electronic circuit is a system of electronic components connected together to perform a specific function. These circuits allow electric current to flow through various paths and are used in nearly all modern electronic devices.
Key Components of an Electronic Circuit:
- Resistors – limit the flow of electric current.
- Capacitors – store and release electrical energy.
- Diodes – allow current to flow in only one direction.
- Transistors – amplify or switch electronic signals.
- Inductors – store energy in a magnetic field.
- Integrated Circuits (ICs) – contain many miniaturized components in a single package.
- Power Source – provides the energy (like batteries or power adapters).
- Wires and Connectors – conduct electricity between components.
Types of Electronic Circuits:
- Analog Circuits – work with continuous voltage and current.
- Digital Circuits – use discrete levels (0 and 1) to represent data.
- Mixed-Signal Circuits – combine both analog and digital components.
Applications:
- Computers
- Mobile phones
- Televisions
- Medical devices
- Automotive systems
- Industrial machines
Realistic Simulation with DCAClab:
DCAClab is a realistic online circuit simulator designed for students, educators, and electronics enthusiasts. It allows users to build, test, and visualize both DC and AC circuits using drag-and-drop components in a virtual lab environment. With real-time simulation and measurement tools like ammeters, voltmeters, and oscilloscopes, DCAClab offers hands-on experience with electronics without physical hardware. It is widely used in educational settings to enhance circuit design and troubleshooting skills.
