Are there different 3 prong dryer cords? Both have three prongs. The two flat prongs closest to the cord are “hot,” each feeding 110/120 volts to total 220/240 volts to the range or the dryer. The third prong (the one furthest from the wire) serves as both the “neutral” and the ground wire. The third prong on a range plug is flat like the other two.
