Ah, I can't remember the exact equations, but it's something Maxwell added to make the law work when current isn't flowing in a wire, like in the gap of a charging capacitor. It fixed the maths by considering changing electric fields.
My own life says you must sometimes add what's missing to complete the circuit. For five years, I've been the 'displacement current' in my family—earning a little from tutoring to bridge the gap between our old radio and the government exam, keeping things going.
