Voltage Divider Calculator

This app calculates the optimum resistor values for a voltage divider circuit, incorporating all resistors in the E12, E24, E48, E96 and E192 series. The standard voltage divider equation is shown below. $$V_{Mid} = \frac{R_2}{R_1 + R_2} \times V_{High}$$ There are 2 modes of operation: Fixed $V_{High}$ and Fixed $V_{Mid}$. For example, if $V_{High}$ is fixed, the app will solve for $V_{Mid}$, using the specified $V_{Mid}$ value as guidance for the optimum resistor ratio $\frac{R_2}{R_1 + R_2}$. Additionally, a specified resistor value can be entered, and the app will only return resistor combinations that include this value. This can be useful if you have a specific resistor value that you'd like to use, but don't know what the other resistor value should be. Note: The specified resistor value must be in the E12, E24, E48, E96 or E192 series.
