Chain Drive with Tensioner Mechanical Demonstration Model Subcategory_Filtration Equipment sized to detect bidirectional milliampere

sized to detect bidirectional milliampere currents in induction

One-ohm 5W wire-wound fixed resistor enclosed in an ABS module with 4mm sockets

5m of twin flex for connection to mains-grade optical-bench setups

the lower-resistance higher-current option in the compact-tube rheostat line

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