2.4.2 Energy Transfer

• What does energy transfer refer to in electrical appliances?

  Conversion of electrical energy
• Energy transfer pathways in electrical appliances are the routes through which energy flows
• Match the appliance with its energy transformation and pathway:

  Toaster ↔️ Thermal Energy via Resistive Heating

  Hair dryer ↔️ Thermal and Mechanical Energy via Fan and Resistive Heating

  Radio ↔️ Electromagnetic and Audio Energy via Circuitry
• What are the three common forms of energy that electrical energy is converted into?

  Thermal, Light, Mechanical
• In a toaster, electrical energy is converted into thermal energy via resistive heating.
• Order the appliances based on their primary energy transformation:

  1️⃣ Toaster: Electrical to Thermal Energy

  2️⃣ Light Bulb: Electrical to Light and Heat

  3️⃣ Fan: Electrical to Mechanical Energy
• Energy transformation in electrical appliances always results in thermal energy.

  False
• Which appliance uses an electric motor to convert electrical energy into mechanical energy?

  Fan
• Match the appliance with its energy transformation and pathway:

  Toaster ↔️ Thermal Energy via Resistive Heating

  Light Bulb ↔️ Light and Heat via Resistive Heating of Filament

  Fan ↔️ Mechanical Energy via Electric Motor
• In a toaster, electrical energy is converted into thermal energy using resistive heating.
• What type of energy is produced by the heating coils in a hair dryer?

  Thermal energy
