Although they are common components, most used in electronic equipment, the capacitors still bring some doubts to technicians and engineers little experienced. When using one type or another and what the differences in characteristics are some of the points which we discuss in this article.
Holes in heating pipes or steam engines and boilers; air leaks in heating or cooling systems; components or heated parts, heating points in electrical installations, all this can be detected on the spot or remotely without the need to place your hand or finger on the spot with this sensitive electronic device. Very small and simple to assemble, plus the advantage of safety has the advantage of reaching difficult locations and giving remote indications.
The determination of the capacitance equivalent to a series capacitor association offers the student of the professionalizing electronic courses the same issues found in determining the resistance equivalent to a parallel association. In fact, we can say that the formulas are equivalent, although they deal with different quantities. However, since the algebraic process which leads to the final result is the same for both cases, when solving problems, the student finds the same difficulties.

In a Bridged or BTL (Bridge Tied Load) configuration, you can quadruple the power of two amplifiers. In other words, two 10 W amplifiers can provide 40 W output.
This circuit can be used as an output interface for personal computers which have the parallel (old) port and also as shield for microcontrollers with the appropriate adaptations. The components used are common.
Everyone knows that the best way to get sine signals is from analog circuits. However, analog oscillators have some "defects" which may be important in certain applications, such as the need for a redesign if we have to change their operating frequency too much.
