The phenomenon you're describing is often associated with electric stoves that have a smooth ceramic or glass surface, known as ceramic glass cooktops. These cooktops are designed to retain heat and have a residual heat indicator to show when they are still hot even after being turned off.
Here's why some electric stoves get hot when turned off while others don't:
Ceramic Glass Cooktops: As mentioned earlier, electric stoves with ceramic glass cooktops are designed to retain heat efficiently. When you cook on these stoves, the ceramic surface heats up, and it takes some time for it to cool down after you turn off the heating element. This retained heat can continue to warm the surface for a while even after the power is switched off.
Coil or Solid Element Stoves: Traditional coil or solid element electric stoves are less likely to stay hot after being turned off. The elements on these stoves heat up quickly, but they also cool down relatively faster compared to ceramic glass surfaces.
Residual Heat Indicator: Many modern electric stoves with ceramic glass cooktops have a residual heat indicator to warn users when the surface is still hot. This indicator helps prevent accidental burns and reminds users not to place heat-sensitive items on the surface until it cools down completely.
Insulation and Heat Distribution: The design and construction of the stove also play a role in how much heat is retained. Stoves with better insulation and heat distribution mechanisms tend to cool down faster than poorly insulated ones.
Size and Power of Heating Elements: The size and power of the heating elements can influence how quickly the stove heats up and cools down. Higher-powered elements might take longer to cool down than lower-powered ones.
Regardless of the type of electric stove you have, it's essential to exercise caution and be aware of the residual heat. Avoid touching the surface until it has cooled down, and use the residual heat indicator if your stove has one. This will help prevent burns and ensure safe cooking practices.
