Cours de physique chimie pour le college (5eme, 4eme, 3eme) 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. Resistors can also be connected together in various series and parallel combinations to form resistor networks which can act as voltage droppers, voltage dividers or current limiters within a circuit. A Typical Resistor Then a potential difference is required between the two terminals of a resistor for current to flow. Standard Resistor Symbols Composition Types of Resistor

Virtuali-Tee donne l’impression de voir ses organes en action L’essor de la réalité augmentée ne semble pas près de s’interrompre. En suivant ce courant, une campagne Kickstarter est lancée : Virtuali-Tee. Pointez votre mobile ou set de réalité virtuelle sur le vêtement et une projection 3D qui simule les organes internes du torse, apparaîtra dessus à travers votre écran. L’idée derrière le projet est de rendre l’apprentissage de l’anatomie plus simple et ludique pour les jeunes, ou même pour les adultes intéressés. Tout bouge : les poumons, le coeur, etc. Les développeurs pensent déjà à plusieurs extensions possibles à Virtuali-Tee, comme calquer les battements du cœur simulé sur le véritable rythme cardiaque du porteur du tee-shirt, grâce à une smartwatch par exemple. Les tee-shirts sont proposés en taille enfant et adulte, et sont fournis pour une contribution de 22 £ ou plus.

Probably the most common source of error in any analog to digital measurement system is improper grounding. To accurately measure an analog signal, the producer of the signal, that is the sensor, and the measuring device, usually an A/D converter in a microcomputer system, must share a common ground reference. In practice, that is often difficult, and the two ground references may differ in voltage by millivolts to volts. Unless they are fully isolated, analog output sensors must refer their output voltages to a ground reference. Referring to Figure 1, the power supply currents create ground differentials of ±ΔV1 and ±ΔV2. Attempts to better tie together the grounds of the sensor and measurement system usually don't help. Mitigating ground loop offsets Ideally, you would reduce noise and ensure measurement accuracy by eliminating ground loops. There are two other solutions. Lets take a closer look at the circuit for the differential amplifier:
