1. The resistance across your (wet) tongue, from one side to the other near the tip, is 375 ? (assume that your tongue is an ohmic material). If you connect two thick copper wires of relatively negligible resistance to the terminals of a 1.5 volt flashlight battery, and place them on opposite sides of your tongue, you will be able to "taste" the electricity as it flows across, producing a sour metallic flavor. What current is flowing through the saliva that coats your tongue?
