The current is doing work against the resistance of the material which makes up the heating element.
Because it has resistance.
-- Whenever electric current flows through a resistance, it loses energy
equal to (current-squared) x (resistance).
-- When we connect components in an electrical circuit, we use wire with
the least possible resistance, so as not to lose energy in the wiring.
-- When we want to warm up the lab, we use wire with significant resistance,
in order to have it dissipate significant energy and radiate heat.

How does a kettle become hot?
A kettle becomes hot by converting electrical energy into heat through a heating element inside the kettle. When the kettle is plugged in and turned on, the electrical current flows through the heating element, which generates heat that warms the water inside the kettle.
What energy is transformed in a hot plate?
Electrical energy is transformed into thermal energy in a hot plate. The electrical current flows through the heating element, which generates heat through resistance, raising the temperature of the hot plate surface.
How does an electric shower work to heat water for bathing?
An electric shower works by passing water through a heating element inside the shower unit. The heating element uses electricity to heat the water as it flows through, providing hot water for bathing.
Does the wire in the electrical cord of an electric kettle have a higher or lower resistance than the heating element inside the kettle?
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.
What makes the air become hot in a hair dryer?
A heating element inside the hair dryer generates heat when electricity flows through it. The air passing over the heating element absorbs this heat, causing it to become hot before being blown out of the hair dryer.
Why does the cord of an electric heater not glow while the heating element does?
The heating element of an electric heater is a "resistor", the cord which conducts the electricity is not. The resistance of the element of an electric heater is very high. As current flows through the heating element, it becomes red hot and glows. On the other hand, the resistance of the cord is low. It does not become red hot when current flows through it.

What part of electric fire gets hot when electricity flows though it?
The heating element in an electric fire gets hot when electricity flows through it. This element is usually made of materials that have high electrical resistance, causing them to generate heat as the electricity passes through.

How does a water heater work to provide hot water in a household?
A water heater works by heating water using a heating element or a burner. The heated water is stored in a tank and is ready for use when needed. When a hot water tap is turned on, the hot water is released from the tank and flows through the pipes to provide hot water for household use.
How does an electric shower head work to provide hot water for showers?
An electric shower head works by heating water as it flows through the unit using an electric heating element. When the shower is turned on, cold water enters the unit and is heated instantly, providing hot water for showers.
What are the common causes of hot water heater noise and how can it be resolved?
Common causes of hot water heater noise include sediment buildup, a malfunctioning heating element, or a loose heating element. To resolve these issues, you can try flushing the tank to remove sediment, replacing the heating element, or tightening the loose element.
