100µF Electrolytic Capacitor Demonstrator with 4mm Terminals Light & Optics_Spectroscopy charge accumulation

charge accumulation

Ten-inch high-speed low-friction pulley on a 12mm aluminum rod

where colored liquid in a U-shaped section shifts measurably as air blown through a constricted glass tube creates pressure differences

Built on a leveled cast-iron base with a dual-angle polymer top

sized for fine-pitch breadboard work where 4mm hardware is too large for the apparatus

100µF Electrolytic Capacitor Demonstrator with 4mm Terminals Light & Optics_Spectroscopy charge accumulationHundred microfarad electrolytic capacitor in an ABS module with 4mm sockets, supplying enough capacitance to make charge and energy storage observable on a slow charging curve.
