Calculate the values of all three currents in the circuit shown in Fig. 2. For the emitter bias circuit shown in Fig. find IE, IC, VC and VE, VCE for β= 85 and VBE= 0.7V. 3. Determine how much the Q-point in Fig. will changeover a temperature range where β increases from 85 to 100 and VBE, decreases from 0.7V to 0.6V. 4. Fig. shows the voltage divider bias method. Draw the d.c. load line and determine the operating point. Assume the transistor to be of silicon. 5. Calculate the emitter current in the voltage divider circuit shown in Fig. Also find the value of VCE and collector potential VC. 6. For the circuit shown in Fig. find the operating point? Given that β = 50 and VBE= 0.7V. 7. The circuit shown in Fig. uses silicon transistor having β = 100. Find the operating point and stability factor. ) for |1:3-( 4) ]Ve 146V Aracy calculattd n preious ques A Vec-Vse loxlo'+ Vee-Tek-Vo -2.40 -20 + |:26X163xloxo3 |.6- |.73 Vee 4.6V = |)2 -(-2) = 4V |.a3 -3 l4-/-J4 6 3 3S Avo)) To duo h Collet-emu voltae when 1 Vce Opeuatinj Point () celudaha dc load uue Vee- Je (hte) = o Vsen Colletr Cunet 0 blad’.
