Step of 5 6.013P The relation between base current saturation current and emitter voltage for active mode operated transistor is, Thermal voltage is 25 mV approximately at room temperature Determine the base current for base-emitter voltage equal to 0.700 V and saturation current Iₛ equal to A and for equal to 50. = = = 0.145 mA The base current for base-emitter voltage equal to 0.700 V and saturation current equal to A and for equal to 50 is 0.145 mA Step of 5 Determine the base current for base-emitter voltage equal to 0.700 V and saturation current Iₛ equal to A and for equal to 200. = = 200 = 36 The base current for emitter voltage equal to 0.700 V and saturation current Iₛ equal to A and for equal to 200 is 36 Thus, the range of base current for B between (50,200) is Step of 5 The common emitter current gain is collector current (ic) base current For equal to 50, base current is 0.145 mA the collector current is, collector current (ic) = base current 50 = ic 0.145x10⁻³ A Ic 7.2 mA Thus, the collector current for equal to 50 is 7.2 mA Step of 5 For B equal to 200 base current is 36 then collector current is, collector current (ic) = base current ic 200 A 7.2 mA Thus, the collector current for equal to 200 is 7.2 mA Hence, the collector current is a fixed value for different values of Step of 5 The relation between collector current, base current and emitter current is,. The emitter current for equal to 50 is, = 0.145 mA + 7.2 mA =7.345 mA The emitter current for equal to 50 is 7.345 mA The emitter current for equal to 200 is, = 36 + 7.2 mA =7.236 mA Thus, the emitter current for equal to 200 is 7.236 mA Hence, the range of the emitter current for between (50,200) is (7.345 mA,7.236 mA)
