What is the difference between an induction cooker dual coil and a single coil?
The main difference between an induction double coil and a single coil is that the resistance of the double coil is higher, and the number of turns is higher and the volume is larger. For relays of the same voltage and contact capacity, the DC relay action coil has no inductive resistance to DC, so if the relay is designed as an AC relay, the relay will burn up immediately after adding DC. To solve this problem, engineers make the relay with more turns (up to 10,000 turns for a 250 volt DC relay, but only about 5,000 turns for an AC relay) and a smaller wire diameter, which makes the action coil resistance larger and reduces the current through the coil, making the action coil less hot and maintaining the same electromagnetic force. In addition, in order to accommodate a larger number of turns, the volume of the relay must be made larger.
