A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit. bipolar transistor has terminals labeled base, collector, and emitter. A small current at the base terminal (that is, flowing between the base and the emitter) can control or switch a much larger current between the collector and emitter terminals.
In general, we can only recommend short-term disability insurance if offered by your employer either for free or at a low cost. Private short-term disability insurance is most likely not worth your money; itâs often just as expensive as long-term disability despite having a shorter coverage period.
