In the last part of the experiment, the Rheostat was used to reduce the current flow through the ammeter and multimeter, since the resistances on the resistor board were quite low. The Total Resistance of the circuit is due to both the Rheostat and the resistor board. When you connected the higher resistance spools, did you notice that the measured current decreased? If so, why do you think that happened?

(I did see a decrease, but why? Please explain!)

Cholera and other diarrheal diseases cause nearly 2 billion cases of diarrhea annually. Cholera toxin and other bacterial toxins cause the intestine to secrete fluid into the lumen of the gut, depleting the extracellular fluid (ECF) volume. If fluid loss is not matched with fluid intake (law of mass balance), the result is severe dehydration, circulatory collapse, and even death. Drinking a rehydration solution is the most rapid and effective way to replace the large volumes of water lost by...
