CORE & COIL BALLAST ADVANCE

An electrical ballast is a device that limits the current through an electrical load. These are most often used when a load (such as an arc discharge) has its terminal voltage decline when current through the load increases. If such a device were connected to a constant-voltage power supply, it would draw an increasing amount of current until it is destroyed or causes the power supply to fail. To prevent this, a ballast provides a positive resistance or reactance that limits the current. The ballast provides for the proper operation of the negative-resistance device by limiting current. Series resistors are used as ballasts to control the current through LEDs.

Various coils are used in restaurant equipment componentry. An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil, spiral or helix. They are used in electrical engineering, in applications where electric currents interact with magnetic fields, in devices such as electric motors, generators, inductors, electromagnets, transformers, solenoid valves, and sensor coils. Either an electric current is passed through the wire of the coil to generate a magnetic field, or conversely an external time-varying magnetic field through the interior of the coil generates an EMF (voltage) in the conductor.

In refrigeration equipment, the "condenser coil" dispels hot air to the outside of the space. The refrigerant then loops back to the compressor, gets cold again, absorbs heat and disperses it to the outside. As long as the compressor is running, the refrigerant keeps up this continuous loop. Extracting heat from the storage space and transferring it to the refrigerant is the function of the "evaporator coil".

In dish washing machines, the steam coil preheats incoming water, reducing the energy needed to heat the water used in the sanitizing rinse.
