and herbivore feeding adaptations for teaching
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
allowing waveforms to be plotted on an oscilloscope or fed into a frequency analyzer
10V Shunt for Galvanometer Coating_Vinyl and herbivore feeding adaptations forTen 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.
