Calculate resistor networks and supply currents for the prototype board: set up a sheet where I enter resistor values and node voltages, compute currents with Ohm’s law and SUMPRODUCT for parallel branches, and provide total supply current so the designer can check ratings.

Before delivering these calculations to the designer, make verification simple: add input cells highlighted for change, include a safety margin calculation, lock formula cells, and supply a simple worked example row so the reviewer can spot a mis-entry or rating breach quickly.
when the reply comes backPush once: ask it to sharpen the weakest part, and to say what it assumed.

Questions people ask

honest answers

Because you rarely think 'I want the redaction tool'. You think 'I have to share this without leaking the client's details'. Start from the need, and the feature finds you.

Real. Every job here was drawn from what people in real roles were actually seen doing in Excel — not a feature checklist.

No. Each page gives you a ready prompt you can paste into an AI assistant, plus the plain steps to do it yourself. Start with either — the goal is the finished job, not the tool.
