An electrical network is an interconnection of electrical components (e.g. batteries, resistors, inductors, capacitors, switches) or a model of such an interconnection, consisting of electrical elements (e.g. voltage sources, current sources, resistances, inductances, capacitances). An electrical circuit is a network consisting of a closed loop, giving a return path for the current. Linear electrical networks, a special type consisting only of sources (voltage or current), linear lumped elements (resistors, capacitors, inductors), and linear distributed elements (transmission lines), have the property that signals are linearly superimposable. They are thus more easily analyzed, using powerful frequency domain methods such as Laplace transforms, to determine DC response, AC response, and transient response.
A resistive circuit is a circuit containing only resistors and ideal current and voltage sources. Analysis of resistive circuits is less complicated than analysis of circuits containing capacitors and inductors. If the sources are constant (DC) sources, the result is a DC circuit.

This video is about the Classification of the electrical network. The electrical network broadly can be classified in five different categories. This classification is based on the properties of the circuit element which are connected in the electrical network and the response of the network to different inputs or excitations. The classification of the electrical network is as follows: 0:56 1.Active and passive network 2:06 2. Unilateral and Bilateral network 3:08 3. Lumped and Distributed network 4:05 4. Linear and Non-linear network 6:59 5. Time invariant and Time variant network This video will be helpful to all the students of science and engineering in understanding the Classification of the Electrical Network.

Before you can flip your light switch to turn on a light, electricity takes quite a journey to reach you. Learn how electricity is transmitted to your home or business and how to stay safe around transmission towers and substations. This video illustrates the anatomy of an electric utility system. AEP - American Electric Power AEP ranks among the nation's largest generators of electricity, owning nearly 38,000 megawatts of generating capacity in the U.S. AEP also owns the nation's largest electricity transmission system, a nearly 39,000-mile network that includes more 765 kilovolt extra-high voltage transmission lines than all other U.S. transmission systems combined. AEP's utility units operate as AEP Ohio, AEP Texas, Appalachian Power (in Virginia, West Virginia), AEP Appalachian Power...

How do you analyze a circuit with resistors in series and parallel configurations? With the Break It Down-Build It Up Method! http://www.jesseleemason.com Music by Millish - Download our music (that's me on the acoustic guitar) at the iTunes Store: https://itunes.apple.com/us/album/millish/id128839547 0:00 INTRO: In this video we solve a combination series and parallel resistive circuit problem for the voltage across, current through and power dissipated by the circuit's resistors. 1:32 BREAK IT DOWN: We redraw the circuit in linear form to more easily identify series and parallel relationships. Then we combine resistors using equivalent resistance equations. After redrawing several times we end up with a single resistor representing the equivalent resistance of the circuit. We then ap...

The installation Evolving Spark Network consists of a grid of electric spark bridges that traverses the whole exhibition space. Together the bridges form a plane with a height of about 3 meters above the floor. The sparks are a metaphor for the electrical impulses by which our nerves communicate information. Just like neurons that form networks in our body, the spark bridges also form an interconnected network. There is no hierarchical process that determines the patterns of the cells but they are the result from relationships between the individual cells of the network. The movements of the visitors in the installation are being detected by means of radio frequent movement detection sensors and used as input for the network. The visitors activate the network and are being invited for a s...

http://josemanuelruiz.net I understand electricity as a complex and chaotic network, as the primary vehicle for the generating of cartographies, physical as well as virtual, that connects us daily and instantaneously to any place in the world. With electricity we are capable of globally extending our central nervous system and linking it immediately with the rest of humanity. I understand electricity as a process, a continual process of creation and relational transformation of material, data and information which we feed on in order to exercise communicative action. I also understand it as being responsible for automation; with electricity a machine becomes autonomous, independent, ceasing to be a simple medium for the artist, and as such becoming the feasible vehicle that allows it to c...

- PROCESS - A short film that is telling of the modern youth "Process" is a commentary on relationships for the social network generation. It plays off the fact that a realtionship does not end, instead there is a constant, up-to-date, stream of information. Whether it is ones newsfeed on Facebook or an Instagram picture, the flow of information is unavoidable. The youth of today is presented with a bittersweet conflict, the social network.

My goal was to turn lights on and off via cell phone text messaging. Using Bob Paauwe's iLink INSTEON software (http://www.bobsplace.com/ilinks/) as well as Twitter (http://www.twitter.com), I was able to network my cell phone with my house's electrical system. The goal is to implement this on a larger scale at the Duke University Smart Home (http://www.smarthome.duke.edu/). Special thanks to Bob Paauwe for developing iLink and helping me with the configuration. Also, thank you to Summize for providing me with API access to Twitter.

Poster pitch by Joke Meijer, Leiden University Medical Center Background: In mammals, a major circadian pacemaker that drives daily rhythms is located in the suprachiasmatic nuclei (SCN), at the base of the hypothalamus. The SCN receive direct light input via the retino-hypothalamic tract. Light during the early night induces phase delays of circadian rhythms while during the late night it leads to phase advances. The effects of light on the circadian system are strongly dependent on the photoperiod to which animals are exposed. An explanation for this phenomenon is currently lacking. Methodology and Principal Findings: We recorded running wheel activity in C57 mice and observed large amplitude phase shifts in short photoperiods and small shifts in long photoperiods. We investigated whet...
