This calculator computes the output voltage based on the input voltage and the resistance values of R1 and R2.
In response to user requests, we have added the ability to calculate the voltage across R1.
In response to user requests, we have added the option to select units such as mΩ, Ω, kΩ, and MΩ.
When actually building the circuit, be sure to take into account the current flowing through the resistor.
Please be careful, as failure to account for the current could cause a fire.

To calculate the resistance values of R1 and R2 based on the input and output voltages, I recommend using the resistance calculation tool provided by Okawa Electronic Design.
