midpiece with mitochondrial spiral
Multi-range AC/DC moving-coil ammeter spanning to 5A with a toggle for AC or DC mode and a double measuring scale
Platinum anode-and-cathode pair fitted in a rubber bung
large-amplitude waves that students can resolve when oscillating the spring by hand for transverse-wave studies
10V Shunt for Galvanometer Coating_Vinyl midpiece with mitochondrial spiralTen volt range multiplier for galvanometer conversion, dropping the bulk of the measured potential across the external resistor so the coil sees only its proportional share of the signal.
