TESTING SEMICONDUCTOR DIODES An ohmmeter has a low-voltage potential place at its leads when measuring resistance. One lead is positive (usually red in color) and the other lead is negative (usually black in color). When positive lead is placed on the anode of a diode and the negative lead on the cathode, this forward resistance (Rf) should be low, since the diode is forward biased. When the leads are reversed resistance (Rr) should be high, since the diode is reverse biased.

Pls correct and fast

Which material is always conductive?   Metal semiconductor Insulator

6 volts are applied along a 2-cm-long semiconductor bar. The average drag speed is 104 cm/sec. What is electron mobility?

The insulators have wider band gap then semiconducotors. This statement is 1. True 2. False

Semiconductor components such as diodes and transistors are easily damaged by the high temperatures of soldering, so care must be taken to protect these components during the soldering process. One way to do this is to use a heat sink to draw heat away from the component without cooling the connection point too much. Heat sinks made out of sheet metal may be temporarily clipped to the component leads, one at a time, to prevent the solder's high temperature from thermally conducting all the way to the component body:   In the absence of a formal heat sink, can you think of any ways to fashion your own ïmpromptu" heat sinks out of commonly available tools and/or objects?

A piece of silver wire has a resistance of 1 ohm. Determine the resistance of alead wire one-third the length and one-third the diameter if the resistivity of lead wire is 30 times that of silver. NOTE: Please explain where did you get the variables so I can understand them. Thank you
