Since the junctions act like diodes they don’t conduct in both directions if you apply a voltage across the two pins.

WebI B is the base current; Emitter Current: The emitter current is the combination of collector & base current. It can be calculated using any of these equations. I E = I C + I B; I E = I … WebFor this Vbe should be 0.7 V. So you can calculate the current flowing through Rb/base now. You know beta already, so you can calculate the collector current, therefore the collector emitter voltage. Based on our initial assumption, the transistor is in active mode.

WebOutput Voltage - (Measured in Volt) - Output voltage signifies the voltage of the signal after it has been amplified. Input Signal - (Measured in Volt) - Input signal which is provided to a linear amplifier. Emitter Resistance - (Measured in Ohm) - Emitter Resistance is a dynamic resistance of the emitter-base junction diode of a transistor. Output Resistance of … WebThe region between cut off and saturation is known as active region. In the active region, collector-base junction remains reverse biased while base-emitter junction remains forward biased. Consequently, the transistor will function normally in this region. Note. We provide biasing to the transistor to ensure that it operates in the active region.
