Working Of Npn Transistor Diagram. Npn transistor structure you can see below. The forward biased is applied across the emitter base junction and the reversed biased is applied across the collector base junction.
Two batteries are used to simplify operation theory. The circuit diagram of the npn transistor is shown in the figure below. I c v cc v ce r l.
Here p type region has very thin layer respect to other two regions.
The working of this transistor can be considered to be complex. Hence the input side emitter base junction is reverse bias and collector base region. As per the circuit diagram the connections are made. A current flowing from the base to the emitter opens the flow of current from the collector to the emitter.
