Peak Voltage Calculator

What is Peak Voltage?

Peak voltage is the maximum value of the voltage in a sinusoidal wave. If you were to draw a sine wave representing AC voltage, the highest point on that wave is your peak voltage.

Knowing the peak voltage helps in designing and understanding electrical systems. It can be the difference between a functioning gadget and component failure. Whether you're an engineer or someone working with electronics, understanding peak voltage is crucial for safety and efficiency.

How to Calculate Peak Voltage

You can calculate peak voltage using either the RMS (Root-Mean-Square) voltage or the average voltage.

From RMS Voltage

[\text{Peak Voltage} = \text{RMS Voltage} \times \sqrt{2}]

From Average Voltage

[\text{Peak Voltage} = \text{Average Voltage} \times \frac{\pi}{2}]

Where:

• Peak Voltage is the maximum voltage in a sinusoidal wave
• RMS Voltage is the root-mean-square voltage, expressing the effective value of a varying voltage
• Average Voltage is the arithmetic mean of the voltage over a cycle

Calculation Example

Using RMS Voltage

Given an RMS voltage of 230V:

[\text{Peak Voltage} = 230 \times \sqrt{2} \approx 325.27\text{ V}]

Using Average Voltage

Given an average voltage of 150V:

[\text{Peak Voltage} = 150 \times \frac{\pi}{2} \approx 235.62\text{ V}]
