5Ω Fixed Resistor Demonstrator with 4mm Terminals Lab Equipment and Supplies_Lab Equipment this lead-acid accumulator stores electrical

this lead-acid accumulator stores electrical energy and recovers it on demand for repeated use across extended lessons

Used to measure induced EMF as a magnet falls through a 100-turn coil on a 15mm acrylic tube

paired with 4mm sockets so iron-filing patterns can be mapped around a current-carrying conductor for Oersted's experiment

and crater within internal rock layers

5Ω Fixed Resistor Demonstrator with 4mm Terminals Lab Equipment and Supplies_Lab Equipment this lead-acid accumulator stores electricalFive ohm fixed resistor in an ABS module with 4mm sockets, sized to drop a low resistance load into a student built circuit without rewiring or component mounting.
