Sum multiple resistors in series or solve the exact resistor gap required to reach your target value. Snaps closing values to real workbench E24 and E96 standards with percentage error.
Frequently asked questions
How do you calculate resistors in series?
The total equivalent resistance of resistors in series is the direct sum of each resistor: R_total = R1 + R2 + ... + Rn.
What is series resistor gap mode?
Gap mode solves for the remaining resistor needed to hit a target total resistance when one or more resistor values are already chosen.
Why combine resistors in series instead of using a single resistor?
Combining standard resistors in series allows builders to synthesize non-standard target values or distribute power dissipation across multiple components.
Does the order of resistors in series matter?
No. Resistors in a pure series string share identical current regardless of order, so the total combined resistance remains unchanged.
