Drinking Tap-water is better than Bottled Water Bottled water is simply water from some sources that a company has placed in a bottle for resale. It can have minimal processing – as in natural spring or mineral water‚ or it can be completely filtered and dematerialized which is to remove minerals in the water to nearly pure‚ and then added minerals back into the water to make it taste better. In these days‚ “we drink 15 times more bottled water today than we did in 1976. According to the NRDC

Solder (/ˈsoʊldə/‚[1] /ˈsɒldə/[1] or in USA /ˈsɒdər/[2]) is a fusible metal alloy used to join together metal workpieces and having a melting point below that of the workpiece(s). Soft solder is typically thought of when solder or soldering is mentioned‚ with a typical melting range of 90 to 450 °C (190 to 840 °F).[3] It is commonly used in electronics‚ plumbing‚ and assembly of sheet metal parts. Manual soldering uses a soldering iron or soldering gun.Alloys that melt between 180 and 190 °C (360

The history of computer development is often referred to in reference to the different generations of computing devices. A generation refers to the state of improvement in the product development process. This term is also used in the different advancements of new computer technology. With each new generation‚ the circuitry has gotten smaller and more advanced than the previous generation before it. As a result of the miniaturization‚ speed‚ power‚ and computer memory has proportionally increased

1st approximation calculations assume an ideal diode. 2nd approximation calculations take into account the voltage drop across the diode. 3rd approximation calculations additionally take into account bulk resistance. Voltage Drop silicon diode .7V germanium diode .3V Bulk Resistance rB = ∆E/∆I A digital multimeter won’t measure the resistance on a diode due to insufficient voltage. The diode check function of a digital multimeter reads the knee voltage. The knee voltage is the voltage at which a forward
