Extracted text: FIGURE shows a schematic diagram of a DC power supply. Assume all the diodes are ideal. A 10:1 D4 D1 240 Vrms O P D3 D2 RL B FIGURE 1 (i) What is the function of the transformer in this circuit? (ii) Find the potential difference between point A and B (VAB) and draw its waveform. (iii) Draw the output voltage (VRL) waveform. (iv) If you measure the voltage drop across RL using a DC voltmeter, what would be the value? (v) What will happen to the bridge rectifier If D3 is opened? Draw the output signal. (vi) What would happen to the output voltage in (iii) if a capacitor is connected between point P and Q? Explain your answer and draw the output waveform. ||
