Revered members,
With the bias setup shown, the positive terminal of the battery repels the emitter holes toward the base, while the negative terminal drives the base electrons toward the emitter. When an emitter hole and a base electron meet, they combine.
For each electron that combines with a hole, another electron leaves the negative terminal of the battery, and enters the base. At the same time, an electron leaves the emitter, creating a new hole, and enters the positive terminal of the battery.
Electron leaving the emitter and going to positive terminal is agreeable on account of opposite polarity, but how an electron leaves the negative terminal of battery and enters base region (N region), since they are of same polarity, i.e negatively charged electron and negative N region. Won't there be repulsion?
