What is the primary function of a capacitor in an appliance motor circuit?
Answer: Store and release electrical energy
A capacitor in an appliance motor circuit stores and releases electrical energy to help start and run the motor efficiently.
Which electrical component is responsible for converting AC voltage to DC voltage in appliances?
Answer: Rectifier
A rectifier is used to convert alternating current (AC) to direct current (DC) in electrical circuits.
What is the role of a thermostat in an appliance?
Answer: Regulate temperature
A thermostat regulates temperature by turning a heating or cooling element on or off based on the set temperature.
Which mechanical component in an appliance helps reduce friction between moving parts?
Answer: Bearing
Bearings are used in mechanical systems to reduce friction and allow smooth motion between moving parts.
What type of motor is commonly used in household refrigerators?
Answer: Single-phase induction motor
A single-phase induction motor is widely used in household refrigerators due to its efficiency and reliability.
Why is grounding important in electrical appliances?
Answer: To prevent electrical shocks
Grounding provides a safe path for excess electricity to prevent electrical shocks and protect users from electrocution.
