Characteristics of NPN Transistors

1. Bipolar Junction: NPN transistors are bipolar junction transistors (BJT), meaning they have a structure consisting of three regions of alternating P-type and N-type semiconductors.

2. Current Amplification: NPN transistors are designed to amplify electrical current, and can be used in a wide range of electronic applications such as amplifiers, switches, and oscillators.

3. Forward Biased: In order to operate, the base-emitter junction of an NPN transistor must be forward biased, meaning that the base must be connected to a positive voltage relative to the emitter.

4. High Input Impedance: NPN transistors have a high input impedance, which means that they are less likely to draw current from the input source, and are therefore less likely to cause a drop in voltage across the source.

5. Inverted Output: NPN transistors are known for producing an inverted output relative to their input.
