Resistance Box 500 Ohms
Product Code : SCL-PLE-11720
Quick Answer: The Resistance Box 500 Ohms is a plug-type laboratory resistance box giving 1 to 500 Ω in steps from non-inductively wound coils, selected with ground taper plugs in brass blocks, for bridge and potentiometer circuits.
Last updated: 18 October 2026
Key Features
- Resistance from 1 Ω to 500 Ω in total.
- Non-inductively wound resistance wire coils.
- Heavy brass blocks with precision-ground taper plugs.
- Intended for low-power bridge and potentiometer use.
Technical Specifications
| Specification | Value |
|---|---|
| Range | 1–500 Ω (cumulative) |
| Coils | Non-inductively wound resistance wire |
| Selection | Taper plugs in brass blocks |
| Application | Low-power bridge and potentiometer circuits |
How It Is Used
Pulling a plug out of its brass block brings the coil beneath it into the circuit, so the total resistance is the sum of the unplugged coils. The box serves as a known resistance in Wheatstone bridge, metre bridge and potentiometer experiments and for checking Kirchhoff’s laws.
Frequently Asked Questions
What range does the Resistance Box 500 Ohms cover?
It provides resistance values from 1 Ω up to a total of 500 Ω.
How is a value set on the Resistance Box 500 Ohms?
Remove the taper plugs above the coils needed; the unplugged coils add up to the resistance in circuit.
