BASIC DIODE ELECTRONICS INTRODUCTION TO DIODES The p-n Junction The p-n junction is a homojunction between a p-type and an n-type semiconductor. It acts as a diode‚ which can serve in electronics as a rectifier‚ logic gate‚ voltage regulator (Zener diode)‚ switching or tuner (varactor diode); and in optoelectronics as a light-emitting diode (LED)‚ laser diode‚ photodetector‚ or solar cell. In a relatively simplified view of semiconductor materials‚ we can envision a semiconductor as having two

inside in a shadowy cold room with their eyes glued to a television with scenes of gory video games of people shooting each other’s heads off. Family dinner talks turn into family members scattered throughout the house entranced in their own little electronic world. The over-use of technology is creating an impatient society and it is also diminishing once-valued personal interaction with others. More often now these days‚ people would rather let a machine take a message instead of answering a call;

Microcontroller Based Home Security A PROJECT REPORT ON “MICROCONTROLLER BASED HOME SECURITY SYSTEM” ABSTRACT Engineering is not only a theoretical study but it is a implementation of all we study for creating something new and making things more easy and useful through practical study. It is an art which can be gained with systematic study‚ observation and practice. In the college curriculum we usually get the theoretical knowledge of industries‚ and a little bit of implementation knowledge

What’s the difference between resistance and resistivity? Resistance is the obstruction offered to the flow of current by a conductor. Resistivity is the obstruction offered to the flow of current by UNIT AREA OF the conductor. So basically‚ resistance is the property of the object (say a copper wire)‚ whereas resistivity is the property of the substance (copper). And so resistance depends upon the properties of the object. Whereas resistivity depends upon the properties of the metal.
