>question: how might i explain the difference between "capital account" and

They're mirror images. A surplus (or deficit) on the current account has to be invested (or financed). So, a country like the U.S. that runs a very large current account deficit, has to borrow that amount abroad; the outflow on the current account is offset by the inflow on the capital account. When you consume more than your income, your debt rises; when you consume less, your savings rise. Or, if you enjoy/suffer an inflow/outflow of capital, you've got to do something with the money: so Mexico in the early 1990s had a capital inflow that was offset by big current account deficits.
