Nope! Negative to positive has to do with Valence bands of an electron. You have negative to positive in ALL electrical circuits, and even AC circuits as AC is a sign wave that goes negative with 180 degrees of the cycle and positive on the other part of the cycle, and each cycle is looking for the other side of the path for current to flow. When the negative side of the cycle occurs, it is more negative than the reference line, and current flows from the more negative side to the reference line (That is where the alternating current comes into play) In my 1967 Dodge Charger there is a power pack that changes 12 volts DC to 230 Volts AC at 250 cycles per second and the power pack runs the Electrolumanence dash guages, so AC is also involved in classic cars technology. And understand that your TV set also has current flow from negative to positive, and there is no battery with plates involved with a TV set.
