Q5 (b) (c) (a) A step-down transformer connected to a bridge rectifier has the following parameters: Nsec Npri = 0.4, Vp(pri) = 120 V, f = 60 Hz Determine the ideal average voltage (VDC), peak inverse voltage (PIV), rms ripple voltage (Vr(rms)) and ripple percentage (r) of this bridge rectifier circuit. Consider a regulator circuit shown in Figure Q5(b) with the following parameters: = 10 ΚΩ, R, = 20 kn, V₁ = 20 V, Vz = 5.6 V R₁ Calculate the output voltage (V), load current (Iz), and total transistor power dissipation. Assuming thre current gain of Q is 100, determine both base current (IB) and collector current (Ic). Vi R₁ +1 Vz Figure Q5(b) RL Analyze the advantage of the regulator circuit as shown in Figure Q5(b).
