How To Use:
  • Fill in all but one box, hit the Solve button and the unfilled box will be computed.
  • Use 'k'|'M'|'G'|'m'. For instance: "1k" for 1000Ω.
  • Use 'Clear' to unfill a box to clear the way for Solve to compute a new value.

How To Use:
  • Fill in all but one box, hit the Solve button and the unfilled box will be computed.
  • In resistor boxes, use 'k'|'M'|'G'|'m'. For instance: "1k" for 1000Ω.
  • Use 'Clear' to unfill a box to clear the way for Solve to compute a new value.
  • Clicking on the IAdj radio buttons, will automatically solve if at least two values are present.
