Description
This premium Plug Type Resistance Box is an indispensable, high-precision instrument engineered specifically for educational laboratories, physics experiments, and electrical testing setups. Featuring a versatile operational range from 0.1 to 10 Ohms, it relies on premium-grade, non-inductively wound Manganin coils known for their exceptional thermal stability and minimal temperature coefficient. The top panel consists of a durable, insulated bakelite plate hosting heavy, precision-machined brass blocks. The plug-type mechanism utilizes accurately ground tapered brass plugs with insulated knobs, ensuring a flawless, tight fit that completely eliminates loose contact errors. Beautifully encased in a rugged, seasoned teak wood case, this resistance box offers maximum durability against daily lab handling while maintaining structural elegance.
Features
:- Ultra Low Contact Resistance: The precision-ground, tapered brass plugs fit snugly into the thick brass blocks, minimizing any stray or unwanted contact resistance.
- Highly Stable Manganin Coils: Standardized non-inductively wound Manganin wire coils provide excellent resistance stability, unaffected by minor temperature fluctuations.
- Robust Wooden Housing: Constructed from premium seasoned teak wood that protects the internal delicate coils from dust, humidity, and physical impacts.
- Clear Value Labeling: Highly legible, crisp white numeric markings on the top panel allow users to easily calculate total resistance at a glance.
Applications
:- Educational Physics Labs: A staple apparatus in high school, college, and university physics laboratories for practical electricity experiments.
- Wheatstone Bridge Experiments: Extensively utilized as the variable resistance arm in standard Wheatstone and Meter Bridge setups.
- Galvanometer Calibration: Used in standard laboratory configurations to calibrate and determine the internal resistance of a galvanometer.
- Electronics Testing: Serves as a reliable, static resistance standard for R&D testing environments and basic circuit prototyping.
