Final answer:
Smartphone, blender, laptop, microwave, and vacuum cleaner are devices that have circuits. The electric energy in these devices is converted into different forms of energy, such as sound, light, mechanical, electromagnetic, and heat energy.
Step-by-step explanation:
Five Devices that have Circuits:
- Smartphone - electrical, sound, light
- Blender - mechanical, heat, sound
- Laptop - electrical, heat, electromagnetic
- Microwave - electrical, electromagnetic, heat
- Vacuum cleaner - electrical, mechanical, sound
These devices have circuits that convert electrical energy into various forms of energy. For example, a smartphone converts electrical energy into sound energy when playing music, light energy when displaying the screen, and electrical energy into heat energy due to battery consumption. A blender converts electrical energy into mechanical energy to blend food, heat energy due to the friction between the blades and the food, and sound energy due to the noise produced.
A laptop converts electrical energy into heat energy due to the operation of the processor, electromagnetic energy when using Wi-Fi or Bluetooth, and electrical energy into sound energy through the speakers. A microwave converts electrical energy into electromagnetic energy to generate microwaves, which in turn convert into heat energy when heating food. A vacuum cleaner converts electrical energy into mechanical energy to create suction, sound energy due to the noise it produces, and electrical energy into heat energy due to the motor's operation.
