Let’s start with three very basic concepts of electricity: namely, electric charge, electric current, and electric circuit. Circuits can get much more complex, consisting of dozens, hundreds, or even thousands or millions of separate components, all connected with conductors in precisely orchestrated ways so that each component can do its bit to contribute to the overall purpose of the circuit. Devices made of semiconductors, notably silicon, are essential components of most electronic circuits. Household electricity is 120 volts (abbreviated 120 V). Electron — A tiny particle which rotates around the nucleus of an atom. In order to understand even the simplest concepts of electronics, you must first understand what electricity is. 4. This is important to know to learn electronics properly. Measured in volts. It is made up of conductors which rotate through a magnetic field to provide voltage or force by electromagnetic induction. That electricity comes from power plants that burn coal, catch the wind, or harness nuclear reactions. Circuits can be in series, parallel, or in any combination of the two. Corona — A corona discharge is an electrical discharge brought on by the ionization of a fluid such as air surrounding a conductor that is electrically charged. Below is a brief overview of the components and their functions. recommended additional information or allow comparison with related terms. The power manifested in tangible form such as electromagnetic radiation, acoustic waves, or mechanical phenomena. Circuit breakers are used in conjunction with protective relays to protect circuits from faults. Ground — The reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth. I recommend you to read it and do the steps to get comfortable with building circuits. Introduction to Electronics xvi 1 I use the word “supposedly” because, in my view, the official rewards for textbook authoring fall far short of what is appropriate and what is achievable through an equivalent Match. There are two types of signals; Analog and Digital. Piezoelectricity — Electric polarization in a substance (especially certain crystals) resulting from the application of mechanical stress (pressure). Ampacity — The maximum amount of electric current a conductor or device can carry before sustaining immediate or progressive deterioration. REFERENCES : 1. The following basic terminologies are used in electronic communication systems: Signal: Information converted into an electrical form suitable for transmission is called a signal. Electronics Notes. Apparent power is the product of the rms voltage and the rms current. Conductor — Any material where electric current can flow freely. We also may know that there’s a third way to measure electricity, called amps. Vars may be considered as either the imaginary part of apparent power, or the power flowing into a reactive load, where voltage and current are specified in volts and amperes. Volt-Ampere (VA) — A unit of measure of apparent power. For example, if a 100W light bulb is used for 4 hours, 0.4kWhs of energy will be used (100W x 1kW / 1000 Watts x 4 hours).

It travels from the power plants to our houses in big cables hung high in the air or buried in the ground. 27 . If you have a term you think we should add, let us know. Circuit — A closed path in which electrons from a voltage or current source flow. Insulator — Any material where electric current does not flow freely. All circuits must create a closed loop that provides a complete path from the source of voltage (in this case, the battery) through the various components that make up the circuit (in this case, the lamp) and back to the source (again, the battery). In a direct current (DC) circuit, or in an alternating current (AC) circuit whose impedance is a pure resistance, the voltage and current are in phase. A solar-powered MW radio 129 38. This is the difference of potential (voltage) between different points in an electrical circuit. Basic Electronics Terms.
