What is the purpose of the following semiconductor crystals in a transistor: emitter, base, and collector?
What will be an ideal response?
The base is always in between the emitter and the collector. The transistors used in automobiles are called bipolar transistors. They have two polarities, electrons and holes. A transistor is either an N-P-N or a P-N-P type. Each layer of the transistor has a connection for an electrical lead. The emitter is the input lead; the output lead is the collector. The base layer, in the center, controls the switching function of the transistor.

What will be an ideal response?
Schneeberger, Inc. is considering two alternatives to increase the acceleration of its linear motor actuators. The initial investment required in alternative X is $200,000 and in Y is $150,000. The MARR = 20% per year; a total of $200,000 is available for investment; and the rates of return are
