An incandescent light bulb transforms electrical energy into light energy by passing an electric current through a filament, which heats up and emits light as a result of its high temperature. LED lights use a semiconductor material to convert electrical energy directly into light energy through a process called electroluminescence.
When electrical energy is passed through a resistor, such as a heating element in a stove or electric heater, the resistance in the material converts the electrical energy into heat energy through a process known as Joule heating. This heat energy raises the temperature of the material, converting electrical energy into thermal energy.
The device that converts electrical energy to thermal energy is an electric heater. It works by passing an electric current through a resistive element, which generates heat due to the resistance of the material. This heat is then transferred to the surrounding environment, raising the temperature of the space.
Hair straighteners typically use electrical energy, which is converted into heat energy to style the hair by passing it through heated plates.
A light bulb transfers electrical energy into light and heat energy when it is turned on. The electrical energy is converted into photons, which emit light when passing through the bulb's filament.

In a hairdryer, electrical energy is converted into thermal energy through a heating element. This thermal energy is then transferred to the air passing through the hairdryer, which helps to dry and style the hair.
The two main types of injury from electrical energy passing through the body are electrical burns and cardiac arrhythmias. Electrical burns occur at the point of contact with the electrical source, while cardiac arrhythmias can result from the disruption of the heart's normal electrical activity. Both types of injuries can be life-threatening and require immediate medical attention.
Electrical energy is converted into thermal energy through the process of resistance heating. This occurs when an electric current flows through a material with resistance, such as a heating element in a toaster or an electric stove. The resistance causes the material to heat up and emit thermal energy in the form of heat.
Materials absorb energy when they take in and store it, while they transmit energy when they pass it through without storing it. Absorption involves the material retaining the energy, while transmission involves the energy passing through the material.
