Electronic Component Problems

Electronic components are long lasting and work well until several things take place. These things we will discuss later however the important things to know at this basic level of understanding is that electronic problems usually start as a glitch that works acceptably and then works intermittently. The intermittent working of an electrical or electronic situation is called a "flying short" in shop talk by a mechanic.



The flying short is the hardest problem to track down and that's why it is so expensive to have an electrical or electronic problem solved.



All electronic systems are designed to distribute small pressure pulses to devices called relays that switch the high pressure  electrical signal. This electrical pressure is called voltage and more technically called Electromotive Force or E in electronic formulation.

 

 

Most all the electronic components (semiconductors) operate in a range of 5 volts dc. There is a variable from 3 to 15 volts dc but the normal operating voltage on a semiconductor component is set at 5 from an engineering standpoint. The more voltage the electronic components run at (pressure) the more flow of current which directly results in heat dissipation in the semiconducting component. Current is made up of electrons which are bits of electrical pressure. It takes a large number of these electrons to accumulate in a capacitor or battery to flow one ampere. An ampere is how many bits pass by one single point in one second, I think the number is around 6.5 billion billion electrons past one point in one second.

The number is large for the electron which is called the electrical potential. It has potential to do work if it is utilized properly within an electrical system. Work takes electricity, big electricity and electronic components produce signals to the main connecting point for large volumes of accumulated electrons or potential current. The important notes right now should note that current flow is the volume or quantity of flowing electrons, and that the electrical voltage is the pressure of the electrons as they build up or are accumulated by a generator in the system of electrical components and devices.

 

 

At this point there is another note to make and it is the fact that electrical energy is used to produce a magnetic field that can be used to push and pull on metal things.

 

 

A magnetic field is produced after a flow of electrical energy and everything electrical is based on this one simple fact. A magnetic field is like a dc system, it has a north and a south and a quantity of something is flowing, the gauss is the magnetic pressure. It takes electrical flow or current and indicated as I in electronic formulations, to produce a magnetic field strong enough to saturate a metal block that ends up being a permanent magnet.

 

 

Bottom line is it takes electrical energy to produce a magnetic field which is termed electromagnetism.
