Figure 2 shows a power supply circuit comprising a transformer coupling the mains voltage on the left to the full-wave rectifier circuit on the right. It is given that the mains voltage (Vmains) is 230 V RMS, the mains frequency (fin) is 50 Hz, the transformer T1 has a ratio of 9:1, the load resistance (RL) is 1 k. and the capacitance of the capacitor (C) is 470 uF. a. Calculate the following: 1. the transformer AC output RMS voltage for V2 ii. the transformer AC output peak-to-peak voltage for V2 iii. the ripple peak-to-peak voltage (Vpk-pk) across the 1 k load resistance. You can assume that the voltage across the resistor RL is: V1 = Vpk-pk 12. b. If the load resistance is reduced to 5002, what happens to the ripple peak-to-peak voltage (Vpk-pk)? fuse chassis RI] = Figure 2 Full-wave rectifier with transformer
