Decade Resistance Box Manufacturer,Supplier and Exporter in India
Product Code : EL-E-10987
A decade resistance box is a versatile lab tool with rotary
switches to dial in precise, variable resistance values (ohms, kOhms)
for calibrating meters, testing circuits, designing filters, and
troubleshooting electronics by substituting components without soldering,
saving time and effort in finding optimal values
Optimized for variable resistance substitution in DC and AC bridge circuits, this non-inductive Decade Resistance Box provides a total resistance of 11,110 Ω. Engineered for secondary and vocational laboratory environments, it adheres to ISO 9001:2015 quality standards. The four-decade configuration allows for precise 1 Ω incremental adjustments, ensuring high-fidelity data acquisition in Wheatstone Bridge and Ohm’s Law experimental modules.

Key Pedagogical Outcomes (Bloom’s Taxonomy)
- Non-inductive
winding technique: Allows students to analyze pure resistance
in AC circuits by eliminating parasitic inductance, supporting Advanced
Electromagnetism curricula.
- 4-Dial
Decade Configuration (1 Ω to 1k Ω): Enables learners to evaluate
circuit behavior across four orders of magnitude, facilitating
high-resolution variable substitution and component modeling.
- 1 Ω
Step Resolution: Permits the synthesis of precise bridge
balance conditions during Wheatstone and Kelvin Bridge experiments,
improving calculation accuracy.
- Twin
4mm Safety Sockets: Supports the application of standard
laboratory patch cords, ensuring secure, low-loss electrical interfacing
and user safety.
