Source sentences:
text: Since the current goes from emitter to base, the base needs to be 0.7V lower than the emitter.
text: Initially when no current is flowing through base, the resistance across CE is very high that no current flows through it.
text: If a small battery is connected to the base as shown in Figure, to forward bias the base-emitter junction, a small current can flow through the base.
text: So, by design, a relatively small current compared to that of emitter's and collector's goes through base (like walking on water).
text: If a current is flowing to the Base, there will be a path from the Collector (C) to the Emitter (E) where current can flow (The Switch is On.)
text: Therefore, the base of an NPN transistor must be connected to positive voltage for current to flow into the base.
text: For PNP transistors the main current goes from collector to emitter and the small controlling current goes from emitter to base, while for NPN transistors the main current goes from emitter to collector and the controlling current goes from base to emitter.
text: Initially when no current is flowing through base, the resistance across CE is very high that no current flows through it.
text: If the input current to the base is too small (for example, it cannot overcome the 65uA in the example above), then no current will flow through the base and thus the transistor will never conduct.
