1. What is Peak Voltage?

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

2. How Does the Calculator Work?

The calculator uses the peak voltage formula:

Where:

• \( V_{peak} \) — Peak voltage (maximum voltage)
• \( V_{rms} \) — Root mean square voltage (effective voltage)
• \( \sqrt{2} \) — Approximately 1.4142 (constant for sine waves)

Explanation: For a pure sine wave, the peak voltage is √2 times the RMS voltage. This relationship comes from the mathematical definition of RMS values.

3. Importance of Peak Voltage Calculation

Details: Knowing peak voltage is important for designing and testing electrical systems, selecting appropriate components, and ensuring insulation can withstand voltage peaks.

4. Using the Calculator

Tips: Enter the RMS voltage value in volts. The calculator will compute the corresponding peak voltage for a sine wave.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between RMS and peak voltage?
A: RMS voltage represents the equivalent DC voltage that would deliver the same power, while peak voltage is the maximum instantaneous voltage.

Q2: Does this formula work for all AC waveforms?
A: No, this specific formula (multiplying by √2) only applies to pure sine waves. Other waveforms have different relationships.

Q3: Why is peak voltage important?
A: It determines the maximum stress on components and insulation in electrical systems.

Q4: What's the peak-to-peak voltage?
A: Peak-to-peak voltage is twice the peak voltage (from maximum positive to maximum negative).

Q5: How do I measure peak voltage?
A: Use an oscilloscope to see the waveform and measure the maximum voltage directly.
