In a transistor collector current is always
WebFig.2 shows the transistor biasing by the use of a feedback resistor. The base bias is obtained from the collector voltage. The collector feedback ensures that the transistor is always biased in the active region. When the collector current increases, the voltage at the collector drops. 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 …

WebGenerally no arrow head is marked for collector since its reverse leakage current is always opposite to the direction of emitter current. 4. Discuss the need for biasing the transistor. For normal operation, base-emitter junction should be forward biased and the collector-base junction reverse biased.
