Narrative and Bridge Troubleshooting Electric Circuits. Narrative I have always had an interest in finding out how all things electrical work. From a very young age I started to fix things electrical around the house and started hooking up house and car stereos and recievers. Once I got my first computer I st had to know how it worked. So I took it apart and ending up trashing it. But that fine day my interest in circuits and circuit boards grew. As I grew older and he computers became

Research Plan Materials and Equipments Making the circuit diagram will be the first step. A temperature sensor will be obtained from Raon, Manila and the other components will be obtained from V&R Electronic Shop at Naic , Cavite. The components will be the capacitors, diode, potentiometer, transistors, resistors,PCB and other materials that will be used in making the product. General Procedure A circuit diagram will be retrieved in the net and then the PCB that will

this way you can still attach the motherboard to the base without worrying about short circuits. Sometimes you may need to use the plastic springs to isolate the screw from the motherboard PCB surface, because the circuit wire may be near by the hole. Be careful, don't let the screw contact any printed circuit write or parts on the PCB that are near the fixing hole, otherwise it may damage the board or cause board malfunctioning.

within a computer may vary from a few thousandths of an inch, as is the case within a single IC chip, to as much as several feet along the backplane of the main circuit board. Over such small distances, digital data may be transmitted as direct, two-level electrical signals over simple copper conductors. Except for the fastest computers, circuit designers are not very concerned about the shape of the conductor or the analog characteristics of signal transmission. Frequently, however, data must be
