I did really bad on a test and need help understanding why. Could you please explain number seven and eight for me? Thank you

**Circuit Analysis of a Boost Converter** **Figure Description:** The diagram represents a Boost Converter with specific parameters. It includes the components: - Two switches labeled S1 and S2. - An inductor (L). - A capacitor (C) across the output. - A load resistor (Rload). - Input voltage ($V_{in}$) and output voltage ($V_{out}$). **Given Parameters:** - $V_{in} = 10V$ - $V_{out} = 20V$ - $R_{load} = 10 \Omega$ - $L = 10 \mu H$ - Switching frequency ($f_{sw}$) = 100 kHz - $C = 100 \mu F$ **Questions:** 5. **For the above Boost converter, what is the duty cycle (for S1)?** Duty cycle ($D$) is calculated using the formula: \[ D = 1 - \frac{V_{in}}{V_{out}} \] Substituting the given values: \[ D = 1 - \frac{10}{20} = 0.5 \] **Answer: D. 0.5** (circled) 6. **What are the average current flowing in the power switches S1 and S2?** The average current ($I_{L_{avg}}$) in the inductor is given by: \[ I_{L_{avg}} = I_{in} + I_{out} \] However, explicit numerical values for $I_{in}$ and $I_{out}$ would be necessary for computation. This educational content provides a fundamental understanding of how to analyze a boost converter circuit and calculate the duty cycle, demonstrating the basic principles of power electronics.
