There are two types of problems with electrical systems. The first is an open. The second is a fault. A fault is a shortened circuit or short circuit for short. A short circuit is when electricity has found a path back to the source other than the intended one. This can happen due to inadvertent contact, or failure of an insulator. Heat is the major enemy of an electrical system. It can create an open circuit by burning open a connection or it can cause a fault in the from of a short circuit by destroying insulation and allowing the electricity to find a newer easier path back to the source. An open circuit will prevent a device from working while a short may also cause a fire or shock.

There is really only one type of electrical fault, overccurents. Overccurents may be a result of overloads (heat), ground faults, or short circuits.
These failures may result in insulation damage, terminal (connection) damage, component damage, even fire.

Faults are generated because of two basic components- either voltage or current. voltage related faults occurs in high voltage systems because in those systems the current keeps low. In low voltage systems the faults occures due to heating effect of current (hea\ting effect is proportional to squire of the current) due to high amount of current.
Majority of faults are generated due to later one.

In a airplane triangle, the sum of the interior triangles is often one hundred eighty ranges. If one attitude is ninety, then the different 2 would desire to upload as much as ninety. ----- Mark the three angles as A, B and C (C being ninety ranges). Mark the factors opposite the corresponding angles as a, b and c (c being the hypothenuse, opposite the ninety degree attitude C). Sin(A) = a/c Cos(A) = b/c Tan(A) = a/b Cos(B) = a/c Sin(B) = b/c Cot(B) = a/b

Most electronic failures are the results of heat. Either part too small or not enough ventilation.
