Devices called thermocouples do this directly.
Boiling water and using the steam to turn turbines which turn generators do this indirectly.
Yes. These both are the different forms of energy (heat energy , electrical energy).These can be converted one to another as per the conservation of energy- " Energy canneither be created nor be destroyed but we can convert one form to another. "Example:1.In thermal power plants, the heat energy is converted into electrical energy.2.In Electric heater, the electrical energy is converted into the heat energy. They can both be used to transfer energy, electricity through a wire or similar conductive material, and heat by conducting through a metal or grill. They can be changed one into the other. For instance, electricity passed through something with high resistance creates heat, whilst heat can be used to make steam and power turbines which make electricity.
thermal/heat energy
This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask for the answer. Earn your diploma. However, a simple resistive load will dissipate heat, thus changing electrical energy to heat energy.
a microwave or a x-ray. Because when the microwave for example is plugged in or turned on is electrical energy and when the food is being cooked is when electromagnetic energy is used. Hope I Could Help :]
All a resistor does is use electrical energy, converting it to heat. so a 10 ohm resistor with 5 volts across it will dissipate 2.5 watts. this will come out as heat, ie, the resistor will get hot.
An electric heater is an example of an instrument that converts electrical energy into heat energy. It uses electrical resistance to generate heat, which is then transferred to the surrounding environment.
An example of electrical energy changing to heat energy is when an electric heater is turned on. The electrical energy powers the heating element in the heater, which then converts the electrical energy into heat energy that warms up the surrounding area.
An incandescent lightbulb is an example of a device that converts electrical energy into light and heat. A loudspeaker is a device that converts electrical energy into sound.
A heat lamp transforms electrical energy into heat and light energy. The electrical energy powers the lamp, which then converts it into heat and light, providing warmth and illumination in the surrounding area.
An example of heat transformation is when a stove burner converts electrical energy into heat energy through resistance heating in the heating coil. This process transforms the electrical energy supplied to the stove into thermal energy, which is then used for cooking food.
An example of electrical energy changing into heat energy is when an electric stove is turned on. The electric current passes through the stove's coils, creating resistance that generates heat. This heat is then used for cooking or baking food.
Think of any device that needs to be plugged in, or that is connected to the power network.Light-bulbs: convert electrical energy to light.Toaster: converts electrical energy to heat.Refrigerator: uses electrical energy as a heat pump (takes heat out of the inside, into the outside).Computer: uses the electrical energy in electronic circuits; eventually the energy gets converted to heat. (In other devices, the electrical energy also gets converted to heat, eventually.)Computer monitor: converts the electrical energy to light energy.Loudspeaker: converts the electrical energy to sound.Etc.
When electrical energy flows through a light bulb, the resistance in the filament causes the electrons to collide with atoms, generating heat energy. This heat energy raises the temperature of the filament, causing it to emit light in addition to heat. So, the conversion of electrical energy to thermal energy primarily happens in the form of heat, with light being a byproduct of this process.
Examples include: electric stoves, toasters, and kettles. These appliances use electrical energy to generate heat for cooking or heating purposes.
Mechanical energy is supplied to a generator from an engine, a steam turbine for example, and converted to electrical energy
An example is the conversion of electrical energy to thermal energy, such as in electrical resistance heating appliances. This process results in the majority of the electrical energy being converted to heat, which may not be the desired outcome in certain applications.
