INFO TECH | NANO TECH | PharmacyTools industrial | Hardware Softwarecommunication | Structural Biomedical electrical | Electronic nanocomputers would operate in a manner similar to the way present- day microcomputers work. The main difference is one of physical scale. More and more transistors are squeezed into silicon chips with each passing year; witness the evaluation of integrated circuits (IC s) capable of ever increasing storage capacity and nanocomputing is part of the emerging field of nanotechnology

possible. Silicon based microelectronic devices have revolutionized our world in the past three decades. Integrated circuits, built up from many silicon devices (such as transistors and diodes) on a single chip, control everything from cars to telephones, not to mention the Internet. Silicon technology is still the most reliable and cost-efficient way to fabricate large microelectronic circuits. Semiconductors have played an amazing role and have impacted technology in many ways. Every technology product

Electrical Symbols and Line Diagrams Chapter 3 Material taken from Chapter 3 of Electric Motor Controls, G. Rockis, 2001 One-Line Diagrams One-line diagram – a diagram that uses single lines and graphic symbols to indicate the path and components of an electrical circuit. One-line diagrams are used when information about a circuit is required but detail of the actual wire connections and operation of the circuit are not. 1 Line Diagrams A line (ladder) diagram is a diagram that shows

* The purpose of this project is to make a resistor from a pencil. I would like or want to figure out how electricity is trapped or contained to form the energy in a circuit to make electrical appliances work. In my experiment: I will create my own resistor out of pencils, along with my own circuit board to see the effects a circuit has on energy. *What a resistor does is slows down the flow of electricity through devices, which now days many devices use: dimmer switches, fan regulators, lights

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

operating temperature and supply voltage of the IC. Generally the current required for triggering is about 0.5uA for a period of 0.1uS. The triggering voltage may be in a range from minimum 1.67V when Vcc=5V to maximum 5V when Vcc=15V. The triggering circuit inside the IC is very sensitive and may be accidently activated due to surrounding noise. To avoid this,

Safety Awareness in Electrical Engineering It is important for students studying to become electrical engineers to be aware of electrical safety measures and hazards. There are several severe, even life-threatening hazards that one could encounter when among electrical equipment. Two main dangers related to dealing with electrical equipment shocks and burns are overloading outlets with too many devices, and neglecting to implement the usage of a Ground-Fault Circuit Interrupter. While outlets
