* Some electric stoves have discrete temperature options such as low, medium, and high. In those stoves, depending on the temperature setting that it is on, a particular circuit is connected and used to heat up the stove to that temperature. When a temperature is adjusted, the circuit that was previously connected is disconnected and a new circuit is connected. In such cases, adjusting the temperature on Yom Tov is forbidden since connecting and disconnecting circuits is an issue of electricity on Yom Tov and if the metal is red hot then additionally it involves igniting a fire and extinguishing it.

* Some electric stoves use a variable temperature and the temperature depends on the voltage going through the circuit, which is adjusting depending on the temperature setting. There is one caveat; the circuit isn't continuously connected. Rather it alternates between being connected and disconnected depending on whether the heating element is at the desired temperature. When the heating element is below the right temperature, the circuit is closed in order to heat up and when it is at the right temperature, the circuit is disconnected for some time. The issue is that if one raises the temperature when the circuit is disconnected, one will cause the circuit to close immediately and if one lowers the temperature when the circuit is closed one will cause the circuit to open immediately.
