What is a voltage divider?
A voltage divider is a basic electrical circuit that uses two resistors in series to divide an input voltage into a lower output voltage. It's commonly used to scale down voltage levels in electronic systems. The output voltage is determined by the ratio of the two resistors.
Can this calculator solve for any missing value, like Vin, Vout, R1, or R2?
Yes! The calculator is designed to solve for any one missing value. Simply input any three of the four known values, and it will automatically calculate the fourth — whether it's the input voltage, output voltage, or one of the resistors.
Does it support different resistor units like kΩ or MΩ?
You can select between ohms (Ω), kilo-ohms (kΩ), and mega-ohms (MΩ) from the dropdown next to each resistor input. The calculator will handle all unit conversions for you.
What happens if I enter invalid or incomplete values?
If the calculator detects incomplete or invalid inputs (e.g., non-numeric values or only two known variables), it will clear the result field and not attempt to calculate. Make sure to input at least three valid values to use the calculator effectively.
Can I use this calculator for AC circuits?
This calculator is specifically designed for DC (direct current) circuits. While voltage division also occurs in AC circuits, those calculations involve reactance and impedance, which are beyond the scope of this simple tool.
