The diagram in figure 3 shows a simplified transistor circuit with a few discrete components. Vcc RB RL C1 C2 IB Vout Vin RE Fig. 3You are given that RB = 1.8 MΩ, RL = 4.7 kΩ, RE = 1 kΩ, C1 = C2 = 10μF and VCC = 15V.(i) How are voltage Vout and current IB are developed. (ii) Why are capacitors C1 and C2 included in the circuit? (iii) Write the load line equation for the circuit in figure 2. (iv) If VCE = 7.5V and αE = 50, calculate IC and IB. (2 marks)
