1. They are household appliances like rice cooker, blender, washing machine, flat iron, etc.
Domestic appliances
Rice Cooker
Resistance heating appliance
Thermostat
A rice cooker is primarily designed for:
Washing clothes and linens
Rice cooking, but it can also cook other foodstuffs and serve related purposes
Blending fruits and vegetables
Ironing fabrics and garments
What defines a resistance heating appliance?
An appliance that uses batteries for wireless operation
An appliance that uses a resistive load as its main part, producing heat when current passes through it
A cooling device that lowers room temperature
A device powered solely by solar energy
A thermostat functions as:
A device that measures voltage in a circuit
A type of switching system controlled by temperature
A timer that counts hours and minutes
An insulator that prevents heat loss
In a resistance heating appliance, the heating element is:
A pan used to hold food
A switch that turns the power on and off
A part that gets hot when the appliance is operated
A component that cools the device during operation
The role of a cast heater in a rice cooker is to:
Deliver heat to the fluro pan where the foodstuffs are located
tore foodstuffs like rice and corn
Insulate electrical wires from moisture
Time the cooking duration automatically
Electrical components in an appliance are:
Parts that perform mechanical functions without electricity
Materials used only for insulation and protection
Non-functional decorative elements
Devices that perform electrical activities when current is applied to the circuit
A mica insulator is characterized by:
Being opaque and flexible for wiring
Its use as a primary heating source
Being a transparent material that splits into thin sheets with excellent insulating and heat-resisting qualities
Its ability to conduct electricity efficiently
Non-electrical components in an appliance are:
Parts that perform designated functions other than electrical applications
Devices that generate electricity from mechanical motion
Wires and circuits that carry current
Sensors that detect temperature changes
An ON/Off switch is used to:
Designate the operating and inoperative state of a device or unit
Regulate the temperature inside the appliance
Measure the power consumption in watts
Insulate heat from escaping the heating element
A timer in an appliance operates by:
Increasing resistance as temperature drops
Opening the electrical circuit after a predetermined period of time elapses
Directly heating the foodstuff in the pan
Splitting into thin sheets for insulation
A thermistor is a device where:
Resistance increases as temperature rises
Resistance decreases as temperature rises due to its high negative temperature coefficient
It acts as a simple on/off switch without temperature sensitivity
t measures power in watts directly
Power in an electrical context refers to:
The physical size and weight of the appliance
The rate at which electric energy is fed to or taken from a device, measured in watts
The material used to insulate the heating element
The duration a timer can operate without interruption
The watt is defined as:
A non-electrical component for storing food
A type of switch for controlling temperature
The basic unit of power which in one second gives rise to energy of one joule
The unit of voltage that powers household appliances
The fluro pan in a rice cooker is:
A heating element that produces resistive heat
An aluminum pan used to store foodstuffs like rice and corn
A transparent insulator made from mica sheets
A device that times the cooking process
