- Resistance Range: 1 to 1000 Ohms
Description
The Educational Lab 1-1000 Ohms Plug Type Resistance Box is a fundamental, high-precision instrument engineered for accurate resistance substitution and calibration workflows. Operating within a comprehensive range of 1 to 1000 Ohms, this laboratory-grade apparatus utilizes a series of carefully adjusted, non-inductively wound Manganin coils. These coils feature an incredibly low temperature coefficient, ensuring stable resistance readings even during prolonged electrical current exposure.
Features
:- Negligible Contact Resistance: Tapered brass plugs sit tightly in matching sockets to eliminate stray contact resistance and connection drift.
- Non Inductive Coil Winding: Coils are meticulously wound using a bifilar technique to cancel out unwanted self inductance and capacitance.
- Excellent Thermal Stability: High-grade Manganin wire guarantees that resistance remains uniform across shifting ambient lab temperatures.
- High Dielectric Safety Panel: Thick ebonite top panel ensures superior electrical insulation and safeguards against high voltage leaks.
Applications
:- Wheatstone Bridge Balance: Serves as a reliable, adjustable known resistance arm for calculating unknown resistances in bridge circuits.
- Potentiometer Calibration: Provides precise step-by-step voltage drops required during the verification and calibration of lab meters.
- Electronic Troubleshooting: Acts as a quick substitution box to find optimal resistance values during prototype circuit designing.
- Galvanometer Protection: Used as a variable series multiplier to prevent sensitive laboratory galvanometers from taking excessive initial currents.
