Which component in heating thermostats helps to prevent temperature overshoot?

Anticipator
Thermistor
Relay
Capacitor

The correct answer is: Anticipator

The anticipator is the component in heating thermostats that is responsible for preventing temperature overshoot. This is because it controls the length of time that the heating elements stay on, preventing them from continuously heating and causing the temperature to go above the desired set point. The other options, such as the thermistor and capacitor, are not directly involved in temperature control. The relay may be involved in turning the heating elements on and off, but it does not actively prevent temperature overshoot.
