Question

Please solve with steps

**Power Supply Circuit Analysis** A power supply circuit is presented in the diagram. The task is to sketch the output voltage \( v_o \) over at least two periods on the plot provided. Important voltages, such as the maximum output voltage, should be labeled on the graph. It's important not to calculate the exact times on the x-axis but ensure that your waveform is plotted according to the period \( T \) labels, which correspond to the input signal period. **Circuit Specifications:** - **Input Voltage:** \( 70V_{\text{RMS}} \), \( 90\text{Hz} \) - **Transformer Turns Ratio:** \( 25:2 \) - **Diodes:** \( D_1 \) and \( D_2 \), with a forward voltage \( V_f = 0.7V \) - **Capacitor:** \( 0.6\text{mF} \) - **Resistor:** \( 140\Omega \) **Graph Explanation:** The graph beneath the circuit is a blank grid designed for sketching the waveform of the output voltage \( v_o \) across the x-axis, which represents time in terms of the period \( T \). The x-axis is marked at intervals of \( T/2 \), \( T \), \( 3T/2 \), and \( 2T \), allowing for the visualization of two full cycles of the waveform. **Instructions for Graphing:** 1. **Waveform Shape:** Due to the presence of diodes, the waveform will likely display a rectified shape corresponding to the capacitor's smoothing behavior. 2. **Key Points to Label:** Indicate the maximum output voltage considering the diode forward voltage drop and transformer characteristics. 3. **Periods Overview:** Ensure that the waveform accurately reflects the periodic nature of the input signal, aligning peaks and troughs appropriately with the \( T \) labels. This exercise combines circuit analysis with practical sketching of waveforms, reinforcing the understanding of rectifier circuits and the effect of components such as transformers, diodes, and capacitors on AC signals.
