2. 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.

3. Aims to reduce polluting elements contained in the
exhaust of a vehicle by the art of catalysis. This is a
device installed in the exhaust pipe, near the motor,
since there remain a gas at elevated temperature.

4. 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.

5. 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.

6. 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.

7. 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.

8. 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%.

9. 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.

10. 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.

11. 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
