circuit

Definition

A circuit is a path that electricity can flow through. It is made up of components, such as wires, resistors, and capacitors, that are connected together.

The components in a circuit are connected in a specific way so that the electricity can flow in a loop. This loop is called a closed circuit. When the circuit is closed, the electricity flows through the components and does work.

When the circuit is open, the electricity cannot flow through the components. This means that the work cannot be done.

There are two main types of circuits: series circuits and parallel circuits.

In a series circuit, the components are connected in a single loop. This means that the electricity has to flow through each component in order to complete the circuit.

In a parallel circuit, the components are connected in separate loops. This means that the electricity can flow through any of the components, and it does not have to flow through all of them in order to complete the circuit.

Circuits are used in many different devices, such as radios, televisions, and computers. They are also used in everyday objects, such as light bulbs and doorbells.

Here are some of the key things to know about circuits:

  • They are a path that electricity can flow through.
  • They are made up of components, such as wires, resistors, and capacitors.
  • The components are connected in a specific way so that the electricity can flow in a loop.
  • There are two main types of circuits: series circuits and parallel circuits.
  • Circuits are used in many different devices and everyday objects.

Different forms of the word

Noun: circuit (plural: circuits).

Adjective: circuitous.

Verb: to circuit.

Adverb: circuitously.

Etymology

The word "circuit" comes from the Latin word "circuitus", which means "a going round". The word "circuitus" is made up of the words "circum" (meaning "around") and "ire" (meaning "to go").

What travels through an electric circuit?

AQA Science Exam Question and Answer

Question:

A circuit is a path that electricity flows through. What are the three main components of an electrical circuit?

Answer:

The three main components of an electrical circuit are:

A source of energy: This could be a battery, a generator, or another device that provides electrical energy.

A conductor: This is a material that allows electricity to flow through it. Metals, such as copper and aluminium, are good conductors.

A load: This is a device that uses electrical energy. Examples of loads include light bulbs, motors, and appliances.

The source of energy provides the electrical current that flows through the circuit. The conductor carries the current from the source to the load. The load uses the current to do work.

The three components of an electrical circuit are essential for electricity to flow. Without a source of energy, there would be no current. Without a conductor, the current would not be able to flow. And without a load, the current would not be able to do any work.

Additional information:

There are many other components that can be found in electrical circuits, such as switches, resistors, and capacitors. However, the three components listed above are the most basic and essential components of any electrical circuit.
