# DB Voltage Ratio Calculator

**Introduction:** Calculating voltage ratios is a crucial task in electrical engineering, especially when dealing with circuit analysis or signal processing. To simplify this process, a calculator can be a handy tool. In this article, we’ll introduce a calculator specifically designed for determining voltage ratios.

**How to Use:** Using the voltage ratio calculator is straightforward. Simply input the values of the primary and secondary voltages, adhering to the prescribed format, and click the “Calculate” button. The calculator will then provide you with the resulting voltage ratio.

**Formula:** The formula for calculating voltage ratio (VR) is:

Where:

*Vsecondary* is the secondary voltage.*Vprimary* is the primary voltage.

**Example Solve:** Suppose we have a transformer where the primary voltage (*Vprimary*) is 120 volts, and the secondary voltage (*Vsecondary*) is 12 volts. Plugging these values into the formula:

So, the voltage ratio in this case is 0.1.

**FAQs:** **Q: Can I use this calculator for any voltage ratio calculation?**

**A: **Yes, this calculator can be used for any scenario where you need to determine the voltage ratio, whether it’s in transformers, voltage dividers, or any other relevant application.

**Q: What units should I use for inputting the voltages?**

**A:** It’s essential to use consistent units for both primary and secondary voltages, such as volts (V).

**Q: Is there any limit to the size of the voltages I can input?**

**A:** No, you can input any numerical values for the voltages as long as they are within the calculator’s supported range.

**Conclusion:** Calculating voltage ratios is a fundamental aspect of electrical engineering, and having a reliable tool like the voltage ratio calculator can greatly simplify this process. With its ease of use and accuracy, it proves to be a valuable asset for professionals and enthusiasts alike.
