What will be an ideal response?
The solid-state relay uses a solid-state component called a thermistor and, therefore, has no moving parts or contacts to wear or burn. A thermistor exhibits a rapid change of resistance when the temperature reaches a certain point. This particular thermistor has a positive coefficient of resistance, which means that it increases its resistance with an increase of temperature.
