Question

In a transistor the base is very lightly doped as compared to the emitter because by doing so
A. The flow across the base region is mainly because of holes
B. The flow across the base region is mainly because of electrons
C. Recombination is decreased in the base region
D. Base current is high

Answer 1

Hint: We can begin to address this question by characterizing what a semiconductor is and what the segments are. It assists us with analyzing the circumstance when we express the working of the transistor. The transistor proceeded to supplant massive vacuum tubes and mechanical relays. The innovation altered the universe of gadgets and turned into the essential building block whereupon all advanced computer innovation rests.

Complete answer:
Transistors are made out of three sections, a base, an emitter, and a collector. The base is the gate regulator gadget for the bigger electrical supply. The collector is the bigger electrical supply, and the emitter is the source for that inventory. By sending fluctuating degrees of current from the base, the measure of current moving through the gate from the collector might be managed.

Thus, a tiny measure of current might be utilized to control a lot of currents, as in an amplifier. A similar cycle is utilized to make the binary code for the computerized processors yet for this situation a voltage limit of five volts is expected to open the collector gate. Along this way, the transistor is being utilized as a switch with a binary capacity: five volts ON, under five volts OFF.

In most transistors, the emitter is intensely doped. Its responsibility is to produce or infuse electrons into the base. These bases are softly doped and extremely thin, it gives the majority of the emitter-infused electrons to the collector.. The collector is so named in light of the fact that it collects electrons from the base.

Therefore, the right answer is option C.

Note: Some of the applications of transistors include the most helpful invention of memory cards in mobile phones, most parts of the latest inventions contain transistors, smartwatches, smartphones, microprocessors, and microcontrollers are some other applications of the transistors. As you move higher on your knowledge of transistors, you will come to meet flip flops and registers which are also the application of transistors.
