Answer / neelabh bajpai

transistor is basically called as a heart of electronic
devices it is almost 56 years old scientist looking for the
name of device which explains its function by its name
hence the name transistor is given meaning trans means
transfer and istor is used for the solid circuitary it uses
basicaaly the transistor provide a path so that input
signal passes from low resistance to high
resisitance.basicaal y it has three operating regions
namely cut off region , saturation region,active region
transistor basicaaly works in active region..

Answer / siva priya

Transistor is 3 terminal semiconductor device. Transistor can act as switch and amplifier.

there are 3 configuration for transistor biasing.
1) Common base
2) common emitter
3) common collector
biasing is technique, provide proper voltage to transistor terminals to make it work.

common emitter configuration is mostly used for switching, CE configuration is good in current, voltage and power gain.

In CE configuration, input is base current(normally micro ampere) output is collector current( inverted milli ampere range). current gain is normally 100 to 300 range. current gets amplified. obvious voltage too amplified.

switching application of the transistor is working saturation and cut off region.

Answer / ravi ranjan

Transistor is a semiconductor device which is used as
amplification or as a switching device.... it is divided as
BJT and UJT..

Consider sinc(x):where sinc(x)=sin (xpi)/xpi. and sinc(x) have max value i.e. unity at x=0 .now if x=0.then pix =0 and sin (pix)=0 at x=0. then above expression sin (xpi)/xpi.should be of 0/0 form i.e. in-determined form. then how sinc(x) is one at x=0. pi is constant.
