1. What is Peak Voltage?

Peak voltage is the maximum voltage value in an alternating current (AC) waveform. It represents the highest point reached by the voltage during each cycle of the AC signal.

2. How Does the Calculator Work?

The calculator uses the peak voltage formula:

Where:

• \( V_{peak} \) — Peak voltage (V)
• \( V_{rms} \) — Root Mean Square voltage (V)
• \( \sqrt{2} \) — Approximately 1.4142

Explanation: The formula converts RMS voltage (the effective DC equivalent voltage) to peak voltage by multiplying by the square root of 2.

3. Importance of Peak Voltage Calculation

Details: Knowing peak voltage is essential for designing and analyzing AC circuits, selecting appropriate components with proper voltage ratings, and ensuring electrical safety in power systems.

4. Using the Calculator

Tips: Enter RMS voltage in volts. The value must be positive and greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between RMS and peak voltage?
A: RMS voltage is the equivalent DC voltage that would produce the same power dissipation, while peak voltage is the maximum voltage reached in the AC cycle.

Q2: Why is the square root of 2 used in the formula?
A: For a pure sine wave, the relationship between RMS and peak voltage is mathematically defined by this constant factor.

Q3: Does this formula work for all AC waveforms?
A: This specific formula applies only to pure sine waves. Other waveforms (square, triangle, etc.) have different conversion factors.

Q4: What are typical applications of peak voltage calculation?
A: Power supply design, audio equipment, motor control systems, and electrical safety assessments all require peak voltage calculations.

Q5: How does peak voltage relate to peak-to-peak voltage?
A: Peak-to-peak voltage is twice the peak voltage, representing the total voltage swing from the most negative to the most positive point.
