Unfortunately with electric stovetops, pans only get heated under the electric source. I love my large cast iron frying pan but only getting heat in the center makes cooking with it a pain/doesn't work well. Gas stoves don't have this problem as the heat from the burner rises up and around the pan heating it all up.
