How do electric kettle switches work?

When a kettle is plugged into an electric outlet and switched on the electric current flows through a metal coil, which is situated either within or under the water. Now, all electric kettles have an automatic shut-off that stops heating the water when they reach boiling point.

What is a resistor in a kettle?

Electric kettles are powered by a heating element which works in the same way an electric range does. The heating element is a resistor—a material that resists the flow of electricity. When electricity flows into the resistor, it is turned into heat. That heat is what heats up the water inside the kettle.

How does a kettle switch off?

This resistance turns electrical energy into heat as it passes through coil. The heat brings the water inside it to boiling point. Some kettles use a thermostat, which prompts them to switch off when the water reaches the right temperature.

What are the components of a kettle?

The parts of an electric kettle include the body, heating element, on/off switch, thermostat, power connection and options (like temperature sensors).

How does a kettle heat water by convection?

Convection is the movement of heat in liquids and gases. The water molecules at the bottom of the kettle gain heat energy from the flame and vibrate faster and move further apart. Their density decreases and the hotter particle rise to the top of the kettle.

What is resistor in a circuit?

The resistor is a passive electrical component that creates resistance in the flow of electric current. In almost all electrical networks and electronic circuits they can be found. The resistance is measured in ohms (Ω).

What circuits are in a kettle?

In a domestic kettle the basic electrical components are:

• Switch.
• Indicator light.
• Heating element.
• Thermostat (Steam)
• Thermostat (Boil Dry)

What is in a kettle circuit?

In a domestic kettle the basic electrical components are: Switch Indicator light Heating element Thermostat (Steam) Thermostat (Boil Dry) In first diagram on the bottom right is the power source; d…

What sensor is used in kettle?

Temperature controlled electric kettle typically uses a temperature sensor (also known as a thermistor) to sense the water temperature and the steam when the water is boiled, and then cut off the electric power if the water temperature reaches the action temperature point or if sufficient amount of steam is detected.

How does the switch on the Kettle work?

The switch will be controlled by an electronic circuit so that the kettle will automatically switch off when the water reaches the required temperature. The electronic circuit will have a variable resistor so that the temperature at which the kettle will automatically switch off can be set by the user . This problem has been solved!

What is the circuit diagram for a whistling kettle?

Whistling Kettle Circuit Diagram. The circuit is based on a simple voltage controlled oscillator formed around T2 and T3. Its operation is best understood by considering the circuit with junction R4/R5 at 0 V and C4 discharged.

What is the resistor on the left side of a kettle?

Next, is the resistor (left hand side) it is represented by a zigzag. In a kettle the heating element is the main resistor, which is located in the water reservoir. As the current passes through the resistor it is converted into heat, this is what boils the water.

What are the basic electrical components of a domestic kettle?

In a domestic kettle the basic electrical components are: Switch. Indicator light. Heating element. Thermostat (Steam)
