Why can my result differ from another source?
Differences usually come from units, rounding, assumptions, local rules, or coefficients used by the other source.

Non-Inverting Op-Amp Gain Calculator: inputs, output, and reproducible example

Non-Inverting Op-Amp Gain Calculator calculates voltage gain from the supplied parameters, with live validation, a readable formula note, and local browser processing.

What this page actually processes

FieldControlDefault exampleValidation role
Ground resistor R1Number1000Ground resistor R1 is read by the browser as a number value before the tool runs.
Feedback resistor R2Number10000Feedback resistor R2 is read by the browser as a number value before the tool runs.

Reproduce the built-in example

Start with Ground resistor R1 = 1000; Feedback resistor R2 = 10000, then run Non-Inverting Op-Amp Gain Calculator. Change one input at a time so the effect on the result remains traceable.

After validating ground resistor r1, feedback resistor r2, the page displays its result in the output workspace and enables the relevant copy or download action.

Formula and variable relationship

Uses 1 + R2/R1 for ideal non-inverting closed-loop gain. The implemented expression is “1+r2/r1”. The page validates ground resistor r1, feedback resistor r2 before formatting the result in ×.

Sensitivity check: change only ground resistor r1 from 1000 Ω to 1,100 Ω. With every other input unchanged, voltage gain moves from 11 to 10.091 ×. This provides a reproducible input-to-result check.

When to use it and how to interpret the result

Non-Inverting Op-Amp Gain Calculator is intended for workflows involving Ground resistor R1, Feedback resistor R2.

Limits and checks before use
