1. A Simple Electrical Circuit Definition (A Basic Overview of What Electrical Circuits Are)

Simple Electrical Circuit Definition

The simplest one-sentence definition of an electrical circuit (or sometimes called an electric circuit) is a closed loop that carries electricity.

What Is a Simple Electrical Circuit?

A simple electrical circuit has 3 things (components) connected together, which include:

  1. a power source,
  2. a conductor,
  3. and a load.

1. Electrical Circuit’s Power Source

The power source is the part of the circuit that produces or stores electricity. For example, a solar panel produces electricity, while a battery stores electricity.

Electricity is a powerful source of energy that is used in many ways. Whether it is powering homes and businesses, or running appliances and machines, electricity is an important part of our lives.

The electric circuit’s power source is the key to getting this energy to where it is needed. This source can come from different places, but most often it comes from the local power company through wires that run to our homes and businesses.

Other power sources that provide electrical energy to circuits are batteries, generators, and solar panels.

2. Electrical Circuit’s Conductor

The conductor is the part of the circuit that allows the flow of the electrical current. The most common example of a conductor is a wire.

A conductor is a material that easily allows electricity to flow through it.

For example, the conductor is the wire that carries the electricity from the battery to the light bulb and back. Copper is a good conductor, while plastic is a poor conductor.

Some common conductors include metal wires, metal plates, and liquids.

3. Electrical Circuit’s Load

The load is the part of the electric circuit that receives electricity for performing some sort of action. For example, a light bulb will receive electricity to produce light.

A load in an electrical circuit can be thought of as anything that consumes electrical power. This can include devices like light bulbs, motors, or any other type of electrical appliance.

When designing a circuit, it is important to ensure that the load is able to handle the amount of power that will be supplied to it. Exceeding the load’s maximum capacity can cause damage to the device and may even create a fire hazard.

Electrical Circuit & Electrons (Negative to Positive)

Electrons are very small particles of matter that have a negative charge of electricity.

To have a complete circuit, electrons from the power source have to travel from its negative side, through the path of the circuit (which includes the conductor and the load), and then back to the power source through its positive side.

Diagram: Electrons move from the negative side to the positive side of the power source.

You can think about a circuit like a racetrack. The cars (electrons) have to go all the way around and back to the starting point (the power source). If you don’t have a closed loop, no electricity can flow around the circuit.

An electrical circuit is a pathway for electrons to flow. It is created by connecting a power source to an object that needs power. The electrons flow from the power source through the wires or other conductors in the circuit, providing power to the object. The object then returns the electrons to the power source, completing the circuit.

Overview: Simple Electrical Circuit Defined

In conclusion, an electronic circuit is a series of electrical components that allow electricity to flow through them.

In other (simpler) words, a current is taking energy out of a power source, like a battery or outlet, and letting it run around in a loop and doing some useful work with it. That work might be something like spinning a fan, powering a TV, or charging a laptop.

There’s an infinite number of ways that you can create circuits. Circuits can be simple or complex and can be used in a variety of applications. This post only showed you the bare-bone basics but hopefully, it helped you to understand what a simple electric current is.

An electrical circuit is a closed loop that contains a power source and one or more loads. The power source provides electricity to the load, and the load uses that electricity to do work. For example, a light bulb is a load that uses electricity to produce light. A simple electrical circuit can be created by connecting a battery to a light bulb with some wire.
