This lecture will help you understand: • Flow of Charge • Electric Current • Voltage Sources • Electrical Resistance • Ohm's Law • Direct Current and Alternating Current • Speed and Source of Electrons in a Circuit • Electric Power • Compact Fluorescent Lamps (CFLs) • Light-Emitting Diodes (LEDs) • Electric Circuits © 2015 Pearson Education, Inc. Flow of Charge • When the ends of an electrical conductor are at different electric potentials—when there is a potential difference— charge flows from one end to the other. – Analogous to water flowing from higher pressure to lower pressure © 2015 Pearson Education, Inc. Flow of Charge • To attain a sustained flow of charge in a conductor, some arrangement must be provided to maintain a difference in potential while charge flows from one end to the other. – A continuous flow is possible if the difference in water levels—hence the difference in water pressures—is maintained with the use of a pump. © 2015 Pearson Education, Inc. Electric Current • Electric current – Flow of charged particles • In metal wires – Conduction electrons are charge carriers that are free to move throughout atomic lattice. – Protons are bound within the nuclei of atoms. • In fluids – Positive ions and electrons constitute electric charge flow. © 2015 Pearson Education, Inc.

  • Current and Resistance
    chapter 27 Current and Resistance . Electric Current . Resistance . A Model for Electrical Conduction . Resistance and Temperature . Superconductors . Electrical Power We now consider situations involving elec- tric charges that are in motion through some region of space. We use the term electric cur- rent, or simply current, to describe the rate of flow of charge. Most practical applications of electricity deal with electric currents. For example, the battery in a flashlight produces a current in the filament of the bulb when the switch is turned on. A variety of home appli- These two lightbulbs provide similar power output by visible light ances operate on alternating current. In these (electromagnetic radiation). The compact fluorescent bulb on the left, however, produces this light output with far less input by electrical common situations, current exists in a conduc- transmission than the incandescent bulb on the right.

(Image copyright Christina Richards, . Used under license exist outside a conductor. For instance, a beam from Shutterstock.com.) of electrons in a particle accelerator constitutes a current. This chapter begins with the definition of current. A microscopic description of cur- rent is given, and some factors that contribute to the opposition to the flow of charge in conductors are discussed. A classical model is used to describe electrical conduction in metals, and some limitations of this model are cited. We also define electrical resistance and introduce a new circuit element, the resistor.

  • Condemnation Without Examination Is Prejudice, Or Words of Wisdom, by John Curl
    Condemnation without Examination is Prejudice, or Words of Wisdom, by John Curl May 2006 John Curl at CES 2001 John Curl at CES 2002. John Curl at CES 2006 2 “I am always giving stuff away for free. It is not in my best interest, and I am continually reminded of this by my associates. It is so easy! I already know it. Yet, when someone tries to patent your suggestion, without your knowledge, trust me, it is a wakeup call.” “By the way, I only developed some of the topologies that you folks use, but I am familiar with all of them. Who do you think first developed most of the circuits that you make here on DIY audio? Do you have any idea?” J. Curl 1 About myself I am an audio design consultant, have been for more than 30 years, and I design several new or improved products every year. I KNOW HOW to develop the topology and get the basic performance from audio circuits. However, this is NOT enough, IF I want to make something other than a mid-fi product. I have proven this to myself by allowing others, in the past, to make the 'minor decisions' such as connectors, layout, wiring, etc and have paid the price of poor sales, and a diminishment of my design reputation. I could NOT MEASURE any problems, with previous decisions, just lost sales and less enthusiastic reviews. I did some of my best work when I worked at AMPEX, as well. What a place! A wonderful technical library.

  • World Electricity Standards Voltage and Frequency
    World Electricity Standards There is no standard mains voltage throughout the world and also the frequency, i.e. the number of times the current changes direction per second, is not everywhere the same. Moreover, plug shapes, plug holes, plug sizes and sockets are also different in many countries. Those seemingly unimportant differences, however, have some unpleasant consequences. Most appliances bought overseas simply cannot be connected to the wall outlets at home. There are only two ways to solve this problem: you just cut off the original plug and replace it with the one that is standard in your country, or you buy an unhandy and ugly adapter. While it is easy to buy a plug adapter or a new "local" plug for your "foreign" appliances, in many cases this only solves half the problem, because it doesn't help with the possible voltage disparity. A 110-volt electrical appliance designed for use in North America or Japan will provide a nice fireworks display - complete with sparks and smoke - if plugged into a European socket. It goes without saying that the lack of a single voltage, frequency and globally standardized plugs entail many extra costs for manufacturers and increase the burden on the environment. Pure waste and unnecessary pollution! Voltage and frequency Europe and most other countries in the world use a voltage which is twice that of the US. It is between 220 and 240 volts, whereas in Japan and in most of the Americas the voltage is between 100 and 127 volts. The system of three-phase alternating current electrical generation and distribution was invented by a nineteenth century creative genius named Nicola Tesla.

The amplifier has been designed to offer to the customer high performances, high reliability and greater simplicity in his operation and maintenance procedures. The amplifiers modules employ all solid state LDMOS technology in order to obtain high gain, wide- band performances, very good linearity, reliability and high efficiency. The equipment design allows the soft degradation (RF power loss) for several transistor faulty: in fact the output combiner uses RF power resistors for unbalancing power dissipation. The unit is enclosed in a cabinet for 19- 6U rackmounting. 50 1.2 TECHNICAL CHARACTERISTICS RF Frequency range 470 - 860MHz Output power 1300W PEP Video/Sound power ratio 10/1 Out stage technology Solid State LDMOS Vision-Sound amplification Common I.M.D. (-8, -10, -16dB) Better than -54dB Standards G, K, N Spurious and harmonics level In compliance with CCIR rec.
