For proper working of a transistor,the voltage at the base region must be more positive than that of the emitter region.The voltage at the collector region, in turn, must be more positive than that of the base region.when voltage is applied to transistor, the emitter supplies electron,which is pulled by the base from the emitter as it is more positive than the emitter.This movement of electrons from emitter to collector creates as flow of electricity through the transistor.The current passes from the emitter to the collector through the base.Thus, adjustment of voltage in the base region modifies the flow of the current in the transistor by changing the number of electron in the base region.
In this way, small changes in the base voltage can cause large changes in the current flowing out of the collector.
We have three transistor element,
a.)Emitter
b.)Base
c.)Collector
This mechanism is how a transistor works.
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail
at full input, if the transistor is working, the value of capacitor will be 0.
A transistor is often referred to as an oscillator because of its ability to transfer resistance. it can also switch off and on repeatedly, mimicking an oscillator.
it is a combination of two transistors connected in series. the emitter of transistor t1 is connected to the base of transistor t2 . now the total circuit acts as a single transistor. this combination will gives high gain, as the gain is multiplied.
A transistor, working in active mode, can amplify a current in a circuit.
A silicon transistor is a transistor made of silicon.
The UM66 is an electronic doorbell. It requires a button for the door, a single transistor, a battery and a speaker.
The active region of a transistor is when the transistor has sufficient base current to turn the transistor on and for a larger current to flow from emitter to collector. This is the region where the transistor is on and fully operating.
A Unijunction Transistor is a transistor that acts solely as a switch.
