Answer the following statement(s) true (T) or false (F)
1. As the base-emitter current begins to rise in the positive direction, the impedance of the collector-emitter of the transistor decreases and current begins to flow through the load resistor and transistor. 2. If a transistor is a linear device, a decrease of base-emitter current will produce a proportional increase in collector-emitter current. 3. In order for the transistor to be able to reproduce the base signal, it must not be biased. 4. A transistor is biased by furnishing a DC current to the base of the transistor and adjusting the current to a point that the transistor is turned half on. 5. A good example of how a simple transistor amplifier may be used in an industrial application is when a relay is to be controlled by a light beam.
