Which electric heating devices in your home do you think have resistors which control the flow of electricity ?

Hint: The conversion of electrical energy to heat energy is known as electric heating. Space heating, cooking, water heating, and industrial operations are all common uses. An electric heater is a device that transforms a current of electricity into heat.

Complete Step By Step Answer:
Every electric heater's heating element is an electrical resistor that operates on the concept of Joule heating, which states that an electric current travelling through a resistor converts electrical energy into heat energy. The active element in most current electric heating devices is nichrome wire; the heating element seen on the right is nichrome wire supported by ceramic insulators.
A resistor is a two-terminal passive electrical component that acts as a circuit element by implementing electrical resistance. Resistors are employed in electronic circuits for a variety of purposes, including reducing current flow, adjusting signal levels, dividing voltages, biassing active components, and terminating transmission lines.
Resistors are widespread in electronic equipment and are common components of electrical networks and electronic circuits. As discrete components, practical resistors can be made up of a variety of compounds and shapes. Resistors are used in integrated circuits as well.
The resistance of a resistor determines its electrical function; typical commercial resistors come in a range of more than nine orders of magnitude. The resistance's nominal value is within the manufacturing tolerance specified on the component.
The devices that use resistors to control the flow of electricity include electric irons, electric ovens, water heaters, and room heaters.

Note:
High-power resistors, which may dissipate hundreds of watts of electrical power as heat, can be found in motor controllers, power distribution systems, and generator test loads. The resistance of fixed resistors varies only minimally with temperature, time, or operating voltage.
