# Source Voltage Calculator

**Introduction**

Calculating the source voltage in electrical circuits is a fundamental aspect of understanding and designing circuits. To simplify this process, we’ll create a source voltage calculator. This interactive calculator will allow users to input relevant values and instantly obtain the calculated result.

**How to Use**

To use the source voltage calculator, follow these simple steps:

- Input the voltage across the resistor (Vr) in volts.
- Enter the current flowing through the resistor (Ir) in amperes.
- Click the “Calculate” button to obtain the source voltage (Vs) result.

**Formula**

The formula used for calculating the source voltage (Vs) is:

*Vs*= *Vr* + *Ir*

Where:

*Vs*is the source voltage,*Vr*is the voltage across the resistor,*Ir*is the current flowing through the resistor.

**Example Solve**

Let’s work through an example to illustrate how the source voltage calculator functions.

Suppose we have a circuit with a voltage across the resistor (*Vr*) of 10 volts and a current through the resistor (*Ir*) of 5 amperes.

The calculated source voltage (*Vs*) is 15 volts.

**FAQs**

**Q: Can I input decimal values for voltage and current?**

**A: **Yes, the calculator supports decimal values for precise calculations**.**

**Q: What units should I use for voltage and current?**

**A:** Enter voltage in volts (V) and current in amperes (A) for accurate results.

**Q: Is there a limit to the values I can input?**

**A: **The calculator can handle a wide range of values, including large and small numbers.

**Conclusion**

Creating a source voltage calculator provides a convenient way to quickly determine the source voltage in electrical circuits. By following the steps outlined above, users can easily input values and obtain accurate results.
