INTRODUCTION The electronics distribution industry is inherently a volatile one because it is based on technologies that are constantly evolving and improving as time passes. The industry has already survived three major technological revolutions and can probably be expecting another one in its long-term future. These "revolutions" usually concern the refinement or replacement of a component that is fundamental to all electronic circuitry. While demand for related component parts remains relatively

Current Affairs Analysis: Electronic Skin Scientists have developed a new technology they believe will be revolutionary in the medical field. They have created an ultra-thin electronic device that attaches to the skin like a temporary tattoo and measures heart rate and other vital signs. The new technology is exciting because it does the same job as the machines used in current hospital monitoring‚ but without the bulk and electrodes. The complicated‚ bulky wiring involved in current hospital monitoring

A Zener diode is a diode which allows current to flow in the forward direction in the same manner as an ideal diode‚ but will also permit it to flow in the reverse direction when the voltage is above a certain value known as the breakdown voltage‚ "zener knee voltage"‚ "zener voltage" or "avalanche point". The device was named after Clarence Zener‚ who discovered this electrical property. Many diodes described as "zener" diodes rely instead on avalanche breakdown as the mechanism. Both types are
