Conduction is the process that transfers thermal energy from the heating element to the bread in a toaster. The heating element gets hot and transfers heat directly to the bread through physical contact, causing the bread to toast.
In a kettle, electrical energy is converted into thermal energy by the heating element. This thermal energy then transfers to the water, raising its temperature and causing it to boil.
In a hairdryer, electrical energy from the power outlet is transferred into thermal energy when the electricity heats up the heating element. The thermal energy is then transferred to the air as it flows over the heating element, resulting in the air being heated. The kinetic energy of the moving air then transfers heat to the hair strands, helping to dry them.
A blow dryer transfers thermal energy mainly by convection and radiation. Convection occurs as the hot air from the dryer rises and displaces cooler air, while radiation transfers heat directly from the heating element to the surrounding environment.
In a stove heating a pot of water, electrical energy is converted to thermal energy as the stove’s heating element produces heat. The thermal energy transfers to the pot and water, raising their temperatures. As the water boils, some of the thermal energy is converted to kinetic energy in the form of water vapor.
When making toast, electrical energy is converted into heat energy as the electric current passes through the heating element in the toaster. The heat energy then transfers to the bread, causing it to toast through the process of thermal conduction.

The process is called radiation. The black fuel effect lumps emit infrared radiation that transfers thermal energy to the objects and occupants in the room, heating them up.
In a hair dryer, electrical energy is converted into thermal energy (heat) by a heating element. The fan inside the hair dryer then transfers this thermal energy to the air, which then blows out heat to dry and style the hair.
The wire in the cord has much lower resistance than the heating element. The heating element is a resistive or resistance heating element. Resistance in the quality of a substance or material that causes it to limit current flow, and it get heated up in the process. The heating element has all but the smallest fraction of the resistance in the circuit, so the heat, that thermal energy that get the water hot, is generated by the resistance of the heating element.
Common issues with the Whirlpool Duet dryer heating element include a faulty heating element, a broken thermal fuse, or a malfunctioning thermostat. These issues can be resolved by replacing the heating element, checking and replacing the thermal fuse if necessary, and testing and replacing the thermostat if it is not functioning properly.
In a kettle, electrical energy is transformed into thermal energy through the process of resistive heating. The heating element inside the kettle uses the electrical energy to generate heat, which raises the temperature of the water inside the kettle.
