NPN Transistor
BC550 NPN Transistor
The BC550 Transistor is a general purpose N-P-N transistor, in which N-P-N transistor electrons work as the primary charge carriers.
BC547 Transistor
BC547 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin.
