Q5 (a) (b) (c) A step-down transformer connected to a bridge rectifier has the following parameters: Nsec Npri +1 = 0.4, Vp(pri) = 120 V, f = 60 Hz Determine the ideal average voltage (VDC), peak inverse voltage (PIV), rms ripple voltage (Vrms)) and ripple percentage (r) of this bridge rectifier circuit. (6 marks) Consider a regulator circuit shown in Figure Q5(b) with the following parameters: R₁ = 10 kn, R₁ = 20 kn, V₁ = 20 V, V₂ = 5.6 V Calculate the output voltage (V), load current (I), and total transistor power dissipation. Assuming thre current gain of Q is 100, determine both base current (IB) and collector current (Ic).
