# Circuit

A circuit is a path that electrons can flow through to create an electric current. In a wire, for example, the electrons flow from the negative terminal of the battery to the positive terminal. In a circuit, the current flows through a closed loop - meaning that the negative and positive terminals are connected, allowing the current to flow continuously.

#### What are the 4 types of circuit?

The four types of circuits are:

2. Microwave circuits
3. Infrared (IR) circuits
4. Optical circuits

#### How does a circuit work?

A circuit is a path that electrons can flow through to power a device. The word circuit comes from the Latin word circuire, which means to go around. In a circuit, electrons flow from the negative (-) terminal of a power source, through a device, and back to the positive (+) terminal of the power source. This flow of electrons is called an electric current. What makes up a circuit? A circuit is an electrical pathway between two or more devices. It typically consists of three components: a power source, a load, and connecting wires. The power source provides the voltage or current needed to power the load. The load is the device that uses the power. The connecting wires carry the current between the power source and the load. Why is it called circuit? The term "circuit" is used to describe an electronic path between two or more points. This path can be created by using a combination of wires, resistors, capacitors, and other electronic components.

### What is circuit and its types?

A circuit is an electrical or electronic path between two or more points. A circuit can be either open (not completed) or closed (completed). The simplest type of circuit is a single conductor in a straight line, but more complex circuits can involve multiple conductors in a variety of shapes and configurations.

There are two main types of circuits: series and parallel. In a series circuit, the current flows through each component in turn. In a parallel circuit, the current flows through several paths simultaneously.

Circuits can also be classified by their function. Some common types of circuits include power circuits, signal circuits, control circuits, and logic circuits.
