Electrical symbol of NPN triode and PNP triode

The circuit symbol map of the NPN triode and the PNP triode, the triode has a total of three electrodes, and the base (represented by B), the collector (represented by c) and the emitter (expressed with E)

Three electrodes of the triode are found to be base (represented by B), collective electrodes (represented by c) and emitter (expressed),


Different representations in the circuit symbol distinguish each electrode of the triode, first remembering an arrow when memory is remembered.
