WebMay 31, 2024 · The collector terminal always has a connection with the positive voltage. The emitter terminal has a connection with the negative supply, and the base terminal manages the ON/OFF states of the transistor based on the voltage applied to it. ... In the collector NPN transistors, the current gain is known as the ratio of the emitter current IE to ... WebA transistor used as a switch (in saturation) will typically have a collector-emitter voltage of about 0.2 volts. Since the base-emitter voltage will be about 0.7 volts, Vs must be at least 0.5 volts above Vcc, plus whatever voltage is required across R2 to get the base current up to the level required. And that base current will be significant. grand view university job openingsWebA transistor in cutoff mode is off -- there is no collector current, and therefore no emitter current.
