Good to know

Which values should I enter?

Use the units shown in each label. Current = voltage / resistance for an ideal resistive circuit.

Are my inputs saved automatically?

No. Recent tools contain tool names only. Inputs and results are stored only when you explicitly choose Save while signed in.

Can I share this tool?

Share the tool link. It opens a blank tool and does not include your private inputs or result.
