FAQ

What is Root Mean Square (RMS)?

RMS is calculated by squaring each number, finding the average, then taking the square root. Formula: RMS = √[(x₁² + x₂² + ... + xₙ²)/n]

What's the difference between RMS and Average?

The arithmetic mean is the sum of numbers divided by count. RMS is more sensitive to larger values and is commonly used to describe the effective value of fluctuating data.

What are RMS applications?

• AC voltage/current effective values
• Standard deviation calculation in statistics
• Audio signal power calculation
• Vibration analysis in engineering
