Know About Components Electric Circuit

When you think of an electric circuit, you probably have an image in your mind. You may even know how one works. But do you really understand what makes them work? If not, it’s time to get up to speed on the ins and outs of circuits so that when something goes wrong with your home wiring system or appliance, you can fix it yourself instead of calling for help from a professional. In this article, we’ll cover all aspects of components electric circuit power source breakers/Fuses Wires Connectors Or Terminals Switches.

Power Source

The power source is the energy that powers the components electric circuit. There are two types of power sources: direct current and alternating current. Direct current (DC) flows in one direction while alternating current changes direction at regular intervals.

Power sources can be either internal or external to your circuit. Internal power sources include batteries and photovoltaic cells; external ones might be solar panels set up on your roof or wind turbines that generate electricity off-grid


In order to understand how a components electric circuit breaker works, you must first know what it is and what its purpose is. A circuit breaker is an electrical device that stops the flow of current through an electric circuit when it becomes overloaded or overheated. It’s basically a switch that turns off automatically when there is too much power flowing through it, which prevents fires from occurring due to overheating wires and appliances.

Circuit breakers come in many shapes and sizes depending on what kind of job they need to do: some are large enough for use in commercial buildings; others are small enough for home use only (these are called fuses). Regardless of their size or function, however, whether they’re fuses or circuit breakers–they all have one thing in common: They’re designed so that if something goes wrong with your electrical system (like if something gets caught on fire), then these safety devices will kick into action immediately by shutting off power completely until repairs can be made!


Wires are the most important part of an electric circuit. Wires transfer electricity from the power source to the load and are usually made of copper. They’re used in circuits to connect components together, so you’ll need to know how many wires are needed for each component in your circuit diagram.

Wires are insulated so that they don’t become short-circuited by touching other wires or metal parts of your project (like screws). This insulation can be thin plastic or rubber sheathing around individual strands of wire, or it could be a solid insulating material like polyethylene foam wrapped around all sides of each piece of wire before being soldered together at their ends with heat-resistant wire connectors called crimps

Connectors Or Terminals

Connectors or terminals are the points where wires are attached to the circuit. There are many different types of connectors and terminals, including screw type, press-fit, solder type, and more. For example:

  • Screw-type connectors have a male or female head that screws into a matching hole at each end of wire insulation. They’re commonly used for joining solid copper conductors together at their ends so they can be connected to terminals on an electrical device such as an outlet or switch box (more on this later).
  • Press fit connectors use pressure from pushing them onto each other instead of threads like with screw connections – they’re often used when space is tight inside equipment cabinets or walls where there isn’t room for screws!


Switches are used to control the flow of electric current. They can be either manual or automatic, and they come in many different shapes, sizes and materials. Switches are used in many applications ranging from household light fixtures to industrial motors.

The most common type of switch is made up of two metal contacts that touch each other when you press down on them with your fingers; this makes an electrical connection between them so that electricity flows through the circuit unimpeded (this is called closing). When you let go of the button or lever that pushes down on these metal contacts (this is called opening), they separate from each other–breaking this connection–and stop electricity from flowing through your circuit until you press down again to close it again later on!


Understanding how circuits work is crucial to your success as an electrician. You need to know how to maintain them and repair them when they break down. If you don’t understand how electricity flows through a circuit, then it won’t matter how much experience or training you have because you won’t be able to identify problems when they arise.
