Question

A sine wave has a peak value of 354 VAC. What is the RMS value?

 

**Question:** A sine wave has a peak value of 354 VAC. What is the RMS value? **Options:** - ○ 250 VAC - ○ 170 VAC - ○ 500.56 VAC - ○ 240 VAC **Explanation:** To calculate the Root Mean Square (RMS) value of a sine wave, use the formula: \[ \text{RMS} = \frac{\text{Peak Value}}{\sqrt{2}} \] Given the peak value of 354 VAC, the calculation is: \[ \text{RMS} = \frac{354}{\sqrt{2}} \approx 250 \, \text{VAC} \] So, the correct answer is **250 VAC**.
