Current flow in npn transistor

WebIn summary, total current flow in the NPN transistor is through the emitter lead. Therefore, in terms of percentage, IE is 100 percent. On the other hand, since the base is very thin and lightly doped, then a smaller percentage of the total current (emitter current) will flow in the base circuit than in the collector circuit. WebThe construction and circuit symbols for both the PNP and NPN bipolar transistor are given above with the arrow in the circuit symbol always showing the direction of “conventional current flow” between the base …
