Question

Name two devices in which electricity is converted into heat.

Answer 1

Hint: The collection of physical phenomena connected with the presence and motion of matter with an electric charge is known as electricity. Electricity and magnetism are both components of the electromagnetic phenomena, as defined by Maxwell's equations. Lightning, static electricity, electric heating, electric discharges, and many more common phenomena are all connected to electricity.

Complete answer:
Any technique in which electrical energy is transformed to heat is referred to as electric heating. Space heating, cooking, water heating, and industrial activities are all common uses.An electric heater is a device that turns electrical energy into heat through the use of electricity.

Every electric heater's heating element is basically an electrical resistor that operates on the Joule heating principle, which states that an electric current passing through a resistor turns electrical energy into heat energy. The active element in most current electric heating systems is nichrome wire.

The right-hand heating element is made of nichrome wire and is supported by a heat-resistant, refractory, electrically insulating ceramic. Radiative heaters, convection heaters, and other types of electric-to-heat conversion devices are some examples. heaters with a fan, system of lighting, Heat pumps, for example, Oven with a microwave.

An energy conversion happens when energy is converted from one form to another. For example, if a device receives electrical energy as an input and produces heat as an output, here is where the conversion happens. One example of electrical energy to thermal energy conversion is the electric lamp.

Note: When energy is transformed from one form to another, such as in a hydroelectric dam, the kinetic energy of water is converted into electrical energy. Energy conservation refers to the fact that though energy can be transported or changed, the total amount of energy does not vary.
