Product Code : SCL-EAE-11232
Quick Answer: Seven Decade Resistance Box puts a selected resistance into a circuit using seven series-connected decades, each set separately, whose values add up to the total resistance.
Last updated: October 2026
Key Features
- Seven independently selectable resistance decades
- Decades connected in series; selected values add to give the total
- Marked switches or rotary controls for setting and repeating values
- Replaces multiple loose resistors during circuit testing
- Supplied with output terminals, a protective earth or guard terminal, and test leads
Technical Specifications
| Specification | Value |
|---|---|

| Resistance arrangement | Series-connected selectable decades |
| Total resistance | Sum of the settings on the seven decades |
| Supplied items | Main unit, output terminals, protective earth or guard terminal, test leads, operating instructions |
About This Product
Each decade covers one order of resistance, so the user builds the required value by setting the decades and adding them, which also shows place value and series resistance at the same time. Within Electrical And Electronics, the box is used with a meter bridge or Wheatstone bridge for resistance comparison and to substitute known values in prototype circuits.
Frequently Asked Questions
Q1. What is a resistance decade?
A resistance decade is a selectable range that represents one order of resistance. With seven decades, the box gives finer adjustment across a wider overall range than a box with fewer decades.
Q2. How is the total resistance set on the Seven Decade Resistance Box?
Set each of the seven decades to the required value and add the selected values together. Because the decades are connected in series, their sum is the total resistance at the output terminals.
Q3. Can it replace individual resistors?
Yes. It can stand in for selected resistance values during testing, teaching and circuit development, as long as its electrical ratings are not exceeded.
