If a cat repeatedly rubs against your cotton slacks on a dry day, the charge transfer between the cat hair and the cotton can leave you with an excess charge of -4.10 μc. (a) how many electrons are transferred between you and the cat? you will gradually discharge via the floor, but if instead of waiting, you immediately reach toward a faucet, a painful spark can suddenly appear as your fingers near the faucet. (b) in that spark, do electrons flow from you to the faucet or vice versa ? (c) just before the spark appears, do you induce positive or negative charge in the faucet? (d) if, instead, the cat reaches a paw toward the faucet, which way do electrons flow in the resulting spark, from faucet to the cat or vice versa?
