Peak Voltage Calculator

What is Peak-to-Peak Voltage?

Peak-to-peak voltage is the total voltage swing in an alternating current (AC) waveform, measured from the lowest negative point to the highest positive point. It represents the full range of the voltage signal.

Formulas for Voltage Calculations

The following formulas are used in voltage calculations:

1. \(V_{peak-to-peak} = 2 \times V_{peak}\)
2. \(V_{peak} = \frac{V_{peak-to-peak}}{2}\)
3. \(V_{RMS} = \frac{V_{peak}}{\sqrt{2}} \approx 0.707 \times V_{peak}\)

Where:

• \(V_{peak-to-peak}\) is the peak-to-peak voltage
• \(V_{peak}\) is the peak voltage
• \(V_{RMS}\) is the root mean square voltage

Calculation Steps

To calculate peak-to-peak voltage from peak voltage:

1. Multiply the peak voltage by 2

To calculate peak voltage from peak-to-peak voltage:

1. Divide the peak-to-peak voltage by 2

To calculate RMS voltage from peak voltage:

1. Divide the peak voltage by \(\sqrt{2}\) (approximately 1.414)

Example

Let's calculate the peak-to-peak voltage for an AC signal with a peak voltage of 5V:

\(V_{peak-to-peak} = 2 \times V_{peak} = 2 \times 5V = 10V\)

Now, let's find the RMS voltage:

\(V_{RMS} = \frac{V_{peak}}{\sqrt{2}} = \frac{5V}{\sqrt{2}} \approx 3.54V\)
