The correct Answer is:
To find the peak voltage (V₀) from the given root mean square voltage (Vₘₛ), we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Given Value**: We know that the root mean square voltage (Vₘₛ) is given as 220 volts. \[ V_{rms} = 220 \, \text{volts} \] 2. **Use the Relationship Between Vₘₛ and V₀**: The relationship between the peak voltage (V₀) and the root mean square voltage (Vₘₛ) is given by the formula: \[ V_{rms} = \frac{V_0}{\sqrt{2}} \] 3. **Rearrange the Formula to Solve for V₀**: To find the peak voltage (V₀), we can rearrange the formula: \[ V_0 = V_{rms} \times \sqrt{2} \] 4. **Substitute the Given Value**: Now, substitute the value of Vₘₛ into the equation: \[ V_0 = 220 \, \text{volts} \times \sqrt{2} \] 5. **Calculate √2**: The value of \(\sqrt{2}\) is approximately 1.414. \[ V_0 = 220 \, \text{volts} \times 1.414 \] 6. **Perform the Multiplication**: Now, calculate the product: \[ V_0 \approx 220 \times 1.414 \approx 311.08 \, \text{volts} \] 7. **Round the Result**: For practical purposes, we can round this to: \[ V_0 \approx 311 \, \text{volts} \] ### Final Answer: The peak voltage (V₀) of the source is approximately **311 volts**. ---
