Catalyst A catalyst is a stainless steel bowl, covered by a metallic shield casing-antipyretic, equally steel, which protects the underbody of the high temperatures reached.
Aims to reduce polluting elements contained in theexhaust of a vehicle by the art of catalysis. This is adevice installed in the exhaust pipe, near the motor,since there remain a gas at elevated temperature.
Oscilograph An oscilograph is an instrument for measuring alternating current, in terms of intensity and voltage, and dump the results into a graph on paper or on a video screen.
Osciloscope An oscilloscope is an electronic measuring instrument for graphical representation of electrical signals that vary over time. It is widely used in electronic signal, often with a spectrum analyzer. Oscilloscopes, classified by their inner workings can be either analog or digital, the result being shown identical in either case, in theory.
Capacitor A capacitor is a passive device, used in electricity and electronics, energy storage capable of sustaining an electric field. Is formed by a pair of conductive surfaces, usually in the form of sheets or plates, in a situation of total effect (ie, that all electrical field lines will start from a stop to the other) separated by a dielectric or by the vacuum. Plates subjected to a potential difference, acquire a certain electric charge, positive and negative one in the other, being zero the variation of total load.
Battery It is called battery, electric battery or electrical storage simply, the device that stores electrical energy using electrochemical methods, which then recharged almost entirely, this cycle can be repeated by a number of times. It is a secondary electrical generator, ie a generator can not function without being previously supplied power, and by what is known as the loading process.
Electric Bulb An electric bulb is a device which produces light from electricity, this conversion can be accomplished by various methods such as Joule heating of a metal filament by fluorescence of certain metals to a shock or by other systems. At present it has technology to produce light at efficiencies of 10 to 70%.
Wire Is called a wire conductor (usually copper) or set them generally coated with an insulating material, while also using the name of light transmitting cable (optical fiber) or mechanical stress (mechanical cable), whose purpose electricidad.S is lead and copper generally manufactured due to the excellent conductivity of this material, although aluminum or has a lower conductivity is more economical.
Storage Battery An accumulator or storage battery is a device that stores energy by electrochemical methods and which can be arranged in the form of electricity. It is necessary to distinguish between rechargeable batteries and disposable batteries or cells. The difference between these types is that the rechargeable batteries allow reverse chemical reaction has occurred during discharge by applying to its electrodes of an electric current from an external generator. In the case of batteries this reversal is not possible so that once downloaded must be discarded.
Welding Welding is a manufacturing process where it performs the joining of two materials (usually metals or thermoplastics), usually accomplished through the coalescence (fusion), in which the parts are welded by fusing both and may add a material molten filler (metal or plastic), to obtain a bath of molten material (the weld) which, upon cooling, becomes a fixed connection. Sometimes the pressure is used in conjunction with heat, or by itself, to produce the weld
