An introduction to electronic components that you will need to build a motor speed are polarized. Note the different length terminals on one of the capacitors. 6. fundamental electronic components used in every electronic product. Resistors. Capacitors There are many different types of resistors used in electronics. function of the active devices as well as the circuit as a whole. Here we shall discuss about some important electronic components and their characteristics.

A battery is a device consisting of one or more cells that produces electricity from a chemical reaction and is used as a source of power. A capacitor is an electronic component made up of two conductors plates , separated by a dielectric or insulating material, which accumulates electric charge when connected to a power source. Common uses for capacitor: Stores electric charge. Acts as a filter to smooth out variations in a direct current.

This magnetic field is generated by its own built-in electromagnet that can be activated by an external circuit.

A resistor is an electronic component that resists or reduces the flow of current in a circuit. There are two kinds, fixed and variable. A variable resistor has a resistance track made of carbon or cermat a mixture of metal and ceramic with a wiper that slides along the track to pick off selected voltages.

Electronic Components - Functions&Symbols

A potentiometer is a variable resistor with three terminals, two of which are connected to the voltage source and the third one to the wiper to select a specific voltage from that source. A rheostat is a variable resistor with two terminals, one of which goes to one end of the track and the other goes directly to the wiper to vary the level of the source. A thermistor is a temperature-sensitive resistor having a high resistance when its cold and a very low resistance when its heated. A thyristor is a semiconductor device that consists of four alternating layers of N-type and P-type material and functions as a bistable switch it starts conducting when its gate receives a pulse of current.

A transformer is a device consisting of two or more coils coupled together by magnetic induction that transfers electrical energy from one circuit to another.

Usual application is to convert a volt AC line into a lower secondary winding voltage. A transistor is an active semiconductor device that controls the flow of electric current and is used in a variety of applications such as a switch, amplifier, rectifier and oscillator.

It has three electrical connections or electrodes which are called base, emitter and collector. A phototransistor is a light-sensitive transistor.

It is an ordinary transistor that conducts electric current when light shines on it. Its base is usually left unconnected in a circuit. Electronics components symbols and its functions. Flag for inappropriate content. Related titles. Understanding Electronic Component Uses and Symbols.

Jumper wires can have male or female ends depending on how they need to be used.

To do this, a soldering iron is the tool you would use. You can choose leaded or lead-free solder in a few diameters. Now its time to talk about the different components that make your electronic projects come to life. Below is a quick breakdown of the most common components and functions they perform. Switches can come in many forms such as pushbutton, rocker, momentary and others. Their basic function is to interrupt electric current by turning a circuit on or off.

Resistors are used to resist the flow of current or to control the voltage in a circuit.

The amount of resistance that a resistor offers is measured in Ohms. A variable resistor is also known as a potentiometer. These components can be found in devices such as a light dimmer or volume control for a radio. When you turn the shaft of a potentiometer the resistance changes in the circuit.

These are often found in exterior lights that automatically turn on at dusk and off at dawn. Capacitors store electricity and then discharges it back into the circuit when there is a drop in voltage. A capacitor is like a rechargeable battery and can be charged and then discharged. A diode allows electricity to flow in one direction and blocks it from flowing the opposite way.

A light-emitting diode is like a standard diode in the fact that electrical current only flows in one direction. The main difference is an LED will emit light when electricity flows through it.

Inside an LED there is an anode and cathode. The longer leg of the LED is the positive anode side. Transistor are tiny switches that turn a current on or off when triggered by an electric signal.

In addition to being a switch, it can also be used to amplify electronic signals. A transistor is similar to a relay except with no moving parts. A relay is an electrically operated switch that opens or closes when power is applied. Inside a relay is an electromagnet which controls a mechanical switch. This circuit contains electronic components like resistors and capacitors but on a much smaller scale. Integrated circuits come in different variations such as timers, voltage regulators, microcontrollers and many more.

Before you design an electronic project, you need to know what a circuit is and how to create one properly. An electronic circuit is a circular path of conductors by which electric current can flow. A closed circuit is like a circle because it starts and ends at the same point forming a complete loop.

In contrast, if there is any break in the flow of electricity, this is known as an open circuit. All circuits need to have three basic elements.

These elements are a voltage source, conductive path and a load. The voltage source, such as a battery, is needed in order to cause the current to flow through the circuit.

In addition, there needs to be a conductive path that provides a route for the electricity to flow. Finally, a proper circuit needs a load that consumes the power. The load in the above circuit is the light bulb. When working with circuits, you will often find something called a schematic diagram.

These symbols are graphic representations of the actual electronic components. Below is an example of a schematic that depicts an LED circuit that is controlled by a switch.

It contains symbols for an LED, resistor, battery and a switch. By following a schematic diagram, you are able to know which components to use and where to put them. These schematics are extremely helpful for beginners when first learning circuits. There are many types of electronic symbols and they vary slightly between countries.

Below are a few of the most commonly used electronic symbols in the US. To find the resistor value, you need to know the voltage and the amps for your LED and battery. Next, you need to find out what voltage your battery is. In this example, we will be using a 9V battery. This will give you a voltage of 7 which needs to be divided by.
