FAQ
How do I account for load when using a voltage divider?
Use the Loaded tab to add the load resistor. The calculator models the R2 ‖ RL equivalent, shows the loaded output voltage, and lets you solve for an R2 value that meets a target voltage.
Is this calculator suitable for safety-critical or production designs?
No. Treat every result as a first-order approximation. Always validate with manufacturer data, EMC and safety requirements, and, if necessary, SPICE or lab measurements before finalising a design.
