Step of 7 6.030E Refer to Figure 6.29 (a) and Figure E6.30 in the text book. The collector of transistor is connected to the base of transistor Draw the following diagram: +15V Figure 1 Step of 7 Refer to Figure 6.29 (b) in the text book Draw the following diagram with current +15 V Figure 2 Step of 7 Calculate the value of Apply Kirchhoffs current law at node Apply Kirchhoffs voltage law for the circuit in Figure 2. (since Calculate the emitter current of the transistor 470 Substitute for 470 (1) Step of 7 Apply Kirchhoffs current law at the node for the circuit in Figure 2. 2.7x10 2.7x10 The expression of emitter current of transistor is, Substitute 100 for and 2.7x10 (2) Step of 7 Equate equations (1) and (2). 470 (101) 101 0.7 2.7x10 470 0.28 0.0396 =7.06 V Step of 7 Therefore, the value of the collector voltage is 7.06 Calculate the value of emitter voltage of the transistor Substitute 7.06 V for =6.36 V Therefore, the emitter voltage is 6.36 V Step of 7 Calculate the collector current, = Substitute 100 for B and 6.36 V for 470 Therefore, the collector current, IS 13.4 mA =0.0134 =13.4 mA
