Types of Resistors including Carbon, Film and Composition The Different Types of Resistor Resistors, ( R ) are the most fundamental and commonly used of all the electronic components, to the point where they are almost taken for granted. There are many different Types of Resistor available for the electronics constructor to choose from, from very small surface mount chip resistors up to large wirewound power resistors. The principal job of a resistor within an electrical or electronic circuit is to “resist” (hence the name Resistor), regulate or to set the flow of electrons (current) through them by using the type of conductive material from which they are composed. A Typical Resistor Resistors are “Passive Devices“, that is they contain no source of power or amplification but only attenuate or reduce the voltage or current signal passing through them. Then a potential difference is required between the two terminals of a resistor for current to flow. Standard Resistor Symbols Composition Types of Resistor Carbon Resistor Carbon Resistor

The Internet of Things is slowly making this type of appliance control easy for anyone to install in their homes, with claps more likely replaced by smartphone taps or algorithmic automation. We’ve already seen a few innovations — from Roost’s smart battery to LightFreq’s light and music control device. Now the LittleBits Smart Home Kit is enabling anyone to make their entire home smart using their existing appliances and without any programming skills. Regular readers of Springwise may remember IFTTT, the service that uses digital ‘recipes’ to automate tasks across web platforms — for example, to post an image to Flickr as soon as it’s been newly synced with Dropbox. Watch the video below for some examples of how the kit can be used: Website: www.littlebits.cc Contact: www.support.littlebits.cc
3 - Condensatori La caratteristica principale di un condensatore è la capacità, ovvero la possibilità di immagazzinare una certa carica elettrica. La capacita a sua volta è la tendenza di due superfici caricate elettricamente, poste in vicinanza ma isolate elettricamente, ad accumulare energia finchè è applicata una differenza di potenziale ai suoi capi (Tensione) ed a rilasciare tale energia quando la differenza di potenziale tra le superfici viene a mancare.Un condensatore è fatto di due piastre di metallo (dette armature) separate da uno strato che non conduce elettricità (detto dielettrico). La capacità di un condensatore dipende dalle sue caratteristiche geometriche (forma, dimensione e distanza delle armature) e dal tipo di dielettrico interposto tra le armature. Un' altro consiglio: per evitare che il condensatore esploda nuovamente a causa della temperatura, potreste pensare di tenere il condensatore alzato dal resto della scheda, in modo da migliorarne l'areazione.
