Heating solid state relay current in what

Heating solid state relay current in car at the base of the main kettle. Relay current is generally used for electromagnetic or solid state, heating solid state relay current directly means that the coil is energized to produce a magnetic field that attracts the moving contacts and affixes them to the static contacts thus turning on the circuit. Solid state is mainly used to generate electrons in the current through the diode, the electrons collide with an object similar to a triode, when the photoelectric strength reaches a certain value, this triode conduction connected to the next circuit.
