    Basic Electronics Components And Their Functions Pdf

    Basic characteristics of transistors Resistors are the most commonly used component in electronics and their of different resistors are shown in the photos. Creative Inquiry Electronics Project - Description of how resistors are manufactured and .. manufactured and the different types of resistors. Basic Electronics into wafers to make electronic devices. .. if there is any circuit/component connected to the gate of a JFET, no current is drawn away from or.

    You will work with a number of basic electronic components when building electronic circuits, including resistors, capacitors, diodes, transistors, and integrated circuits. Here is a brief overview of the functions of each of these basic electronic components. Resistors A resistor is a component that resists the flow of current. If you put resistors next to a penny, you get an idea of how small they are. Capacitors Next to resistors, capacitors are probably the second most commonly used component in electronic circuits. A capacitor is a device that can temporarily store an electric charge. Capacitors come in several different varieties, the two most common being ceramic disk and electrolytic.

    Capacitor Find the capacitor symbol in the schematic symbols overview. You can think of a capacitor as a battery with very low capacity.

    You can charge and discharge it just like a battery. The capacitor is often used to introduce a time-delay in a circuit. For example to blink a light.

    There are many capacitor types.

    Most commonly, we divide them into polarized and non-polarized capacitors. We use LEDs to give a visual feedback from our circuit. For example to show that the circuit has power. But, you can also used them to make cool light-show circuits. A very common circuit to build as a beginner is the blinking light circuit. Transistor Find the transistor symbol in the schematic symbols overview. This is probably the hardest of the basic electronic components to understand.

    Basic Electronic Components Used in Circuits

    Where, base terminal is responsible for activating the transistor, emitter terminal is the negative lead and collector terminal is the positive lead. Transistors Integrated Circuit The short form of an integrated circuit is IC and sometimes it is also called as microchip.

    The Integrated circuit is a semiconductor device, where loads of resistors, capacitors, and transistors are fabricated. It can function as an oscillator, microprocessor, amplifier, and timer. An IC is categorized as either linear or nonlinear depending on its application. These linear ICs are used as audio frequency and radio frequency amplifiers.

    Digital ICs operate at only a few defined states, rather than over a continuous range of signal amplitudes. The applications of integrated circuits include computers, modems, computer networks and frequency counters. The basic structure of digital integrated circuits is logic gates, which work with binary data. Integrated Circuit Relays Relays are electromechanical switches that are used to control the circuits by using a low power signal.

    The relays comprise of an electromagnet, an armature, a series of electrical contacts and a spring. First relays were used as amplifiers in long distance telegraph circuits. There is no electrical connection between the two circuits in the relay because they are connected through magnetic connection.

    Relays are used to perform logical operations in telephone exchanges and computers etc.

    There are two kinds. It has three electrical connections or electrodes which are called base. 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.

    The unit of measurement is called volt V. A resistor is an electronic component that resists or reduces the flow of current in a circuit.

    Its base is usually left unconnected in a circuit. 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.

    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. A relay is an electromechanical device having one or more contacts that are opened and closed by a magnetic field. A rheostat is a variable resistor with two terminals.

    A potentiometer is a variable resistor with three terminals.

    It is an ordinary transistor that conducts electric current when light shines on it. 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 phototransistor is a light-sensitive transistor. Usual application is to convert a volt AC line into a lower secondary winding voltage. Voltmeter A voltmeter is a measuring instrument used to measure the potential difference or voltage between two points in an electric circuit.

    This magnetic field is generated by its own built-in electromagnet that can be activated by an external circuit. A microphone is a transducer or sensor that converts sound into an electrical signal. Usual application is in transistor bias-stabilization circuits and also widely used as inrush current limiters.
