Decade Resistance Box
Easily control circuit resistance
The Decade Resistance Box is an array of precision variable resistors used to control resistance in DC circuits for physics and electronics experiments. With four smooth-turning decade dials, resistance can be set from 1 Ω to 9999 Ω in 1 Ω increments, making it easy to fine-tune experiments and collect reliable quantitative data. Built with 1% tolerance resistors, 4 mm safety sockets, and classroom-ready durability, this resistance box transforms abstract circuit theory into hands-on discovery.

FAQ
Frequently Asked Questions
What is a decade resistance box used for?
A decade resistance box is a variable resistor used to precisely control resistance in an electrical circuit. It allows students to select exact resistance values for experiments such as verifying Ohm’s Law and analyzing circuit behavior without changing individual resistors.What resistance range does this unit provide?
The Lascells Decade Resistance Box provides adjustable resistance from 1 Ω to 9999 Ω in 1 Ω increments using four decade dials.Can this be used as a potential divider?
Yes. With its 4 mm sockets, the unit can function as a potential (voltage) divider for investigations involving output voltage and ratio analysis.Is it accurate enough for quantitative labs?
Yes. The resistors are rated at 1% tolerance, making it suitable for precise measurements and verification experiments such as Ohm’s Law and RC circuit analysis.What is the maximum current and power rating?
The maximum current is 0.35 A, with a continuous power rating of 1 W.What is the difference between a decade resistance box and a rheostat?
A decade resistance box allows resistance to be set in precise stepped increments using fixed resistors, while a rheostat provides continuously variable resistance using a sliding contact. Decade boxes are typically more precise for quantitative experiments.Warning: California Residents
