How Do You Use Transistors In Electronic Circuits?
A transistor uses a small voltage or current to direct the flow of a much larger current. A field-effect transistor uses an electric field to control the conductivity of a semiconducting material. A bipolar junction transistor relies on electrons and holes to control the current flow. The following steps will show how to use transistors in electronic circuits. Study the basic function of a transistor. Current flows from the emitter to the collector if the voltage from the base exceeds a certain value. In a switch, the base and emitter voltage is the same, and the current is either off or on depending upon the base voltage. In an amplifier, small changes in the base voltage produce a large change in the collector voltage. Perform electronic switching with transistors. A switched-mode power supply is a high-power application of this function and a logic gate is a low-power application for switching. Employ bipolar junction transistors in amplifiers today.
