Cover photo by Thomas Scarborough, reproduced by permission of Everyday Practical Electronics. Ferroresonance — (nonlinear resonance) a type of resonance in electric circuits which occurs when a circuit containing a nonlinear inductance is fed from a source that has series capacitance, and the circuit is subjected to a disturbance such as opening of a switch. These Electronic components are basic electronic parts packaged in a discrete form with two or more connecting leads or metallic pads. An RF signal probe 140 41. 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). After all, the whole purpose of electronics is to get electricity to do useful and interesting things. Hertz — A unit of measure for frequency. Electromotive Force — (EMF) A difference in potential that tends to give rise to an electric current.

MIT OpenCourseWare is a free & open publication of material from thousands of MIT courses, covering the entire MIT curriculum.. No enrollment or registration. It is therefore in the interest of anyone involved in electronic circuit design to have the ability to develop filter circuits capable of meeting a given set of specifications. The goal was to give you a basic understanding of how some of the electronic components of a motor speed controller work. A low-light indicator 146 43. Silicon, germanium and carbon are the semiconductors most frequently used in electronics. But all circuits must obey the basic principle of a closed loop. Electric current flows more easily in some types of atoms than in others. Semiconductor — A solid substance that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects. Exists in an AC circuit when the current and voltage are not in phase. Conductive materials, such as metals, have a relatively low resistance. From there, we plug in power cords to get the electricity into the electrical devices we depend on every day. "Basic" spacing is nominal and can change with conditions. ACCUNET Switched Digital Services: High-speed dial-up digital data services offered by AT&T for full duplex digital transmission at speeds of 56, 64, 384 and 1536 kbps.

Basic Electronics Tutorials and Revision is a free online Electronics Tutorials Resource for Beginners and Beyond on all aspects of Basic Electronics Circuit Breaker — An automatic device for stopping the flow of current in an electric circuit. Inductance — The property of a conductor by which a change in current flowing through it induces (creates) a voltage (electromotive force) in both the conductor itself (self-inductance) and in any nearby conductors (mutual inductance). This is important to know to learn electronics properly. 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. 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. Below is a brief overview of the components and their functions. If a current completes one cycle per second, then the frequency is 1 Hz; 60 cycles per second equals 60 Hz. The sulfuric acid - water solution in a storage battery is an electrolyte. By Doug Lowe . In terms of computing, bandwidth is the maximum rate of data transfer across a given path. Measured in volts.
