Description
The Cometek 1 to 100 Ohms Plug-Type Resistance Box. Purpose built for junior schools, high school physics laboratories, and introductory engineering colleges, this classic analog laboratory instrument offers highly dependable fractional and decade resistance tuning. The core mechanics of the device rely on premium Constantan wire coils, wound non-inductively to cancel out stray magnetic interference and deliver steady readings under shifting lab temperatures. The top panel layout features solid, heavy brass blocks separated by precise air gaps. When a tapered plug is seated into a gap, current bypasses the underlying coil seamlessly; removing the plug instantly forces the current through the corresponding resistance value. Secured in a beautiful, seasoned teak wood case, this robust instrument ensures years of dependable classroom service.
Features
:- Minimal Contact Resistance: Extra thick machinery grade brass block connectors keep terminal resistance at an absolute minimum.
- Non-Inductive Double Winding: Coils are carefully looped back to neutralize self induction effects during transient or low frequency AC current testing.
- Insulated Grip Handles: Tapered ebonite plug-tops offer high electrical safety and an ergonomic grip for fluid plug manipulation.
- Durable Binding Posts: Equipped with two heavy-duty, screw-type brass output terminals designed to hold banana plugs or standard patch cords firmly.
Applications
:- Introductory Physics Labs: A staple piece of equipment for high school science fairs, basic technical training institutes, and electronics hobby workshops.
- Circuit Troubleshooting: Used by electronics technicians as a reliable quick-substitution load to diagnose small power paths and sub-circuits.
- Metre Bridge Experiments: Functions as the known resistance box arm when tracking specific resistance and resistivity of unknown sample wires.
