Transistors are turned off while working in the cut off region and turned on while working in the saturation region.
Transistor d313 circuit diagram application datasheet.
2sd313 datasheet pdf 1 1.
A voltage or current applied to one pair of the transistor s terminals controls the current through another pair of terminals.
In most of the applications due to irregular loads the output voltage produced has fluctuations in it which can lead to damaging loads.
I am very confused about use of transistor why we need it in every circuit.
Now my doubt in this article is that in the example of circuit diagram why we need transistor be spite of current flow without a transitor and led turns on so why we connect a transistor and then apply 0 7v source why we need it all that.
