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.

Hi dears, i work with E// switches since a bit time,i faces a problem with AFFILE output,when i get the out put (with Hex code) and i try to convert it to ASCII code it gives me the correct values but the data is not arrange correctly,there is some tabs,spaces and by result the data is shifted is there any advice for this case thanks & regards
