voltage divider

What does this calculator do?

There is a familiar formula for the voltage gain of a voltage divider formed by two resistors: A = R2 / (R1 + R2). Not so familiar are the formulas for determining the value of R1 or R2 when a specific amount of attenuation is desired. Here is a calculator that determines the unknown resistor value.
