A transistor controls current flow: in BJTs, base current regulates collector-emitter current; in FETs, gate voltage controls source-drain flow.
How transistor works?
A transistor is a fundamental electronic component that can function as both a switch and an amplifier. It regulates the flow of electrical current and is crucial for modern electronics. Transistors consist of three main parts: the base, the collector, and the emitter. Think of it as a water valve, where a small amount of electricity (the base current) controls a much larger current (flowing between the collector and emitter). The amount of current flowing through the gate from the collector can be controlled by sending different amounts of current from the base. This allows for the regulation of enormous currents, such as those in amplifiers, with extremely small currents. The identical procedure is used to generate the binary code for digital processors; however, in this instance, a voltage threshold of five volts is required to open the collector gate. The transistor is being utilized in this fashion as a binary switch with the following states: five volts "ON," less than …
