It is right microwave. Only certain types of microwaves use batteries. All phones, radios, and definately flashlights use batteries.
Yes, you are correct. A battery is not used in a microwave.
To determine which devices do not use batteries among flashlight, microwave, portable radio, and cell phone, we can analyze each device's power source.
1. Flashlight: Flashlights typically use either disposable or rechargeable batteries as their power source. Therefore, flashlights do use batteries.
2. Microwave: Microwaves, on the other hand, do not use batteries. They are powered by electricity and are usually plugged into a power outlet.
3. Portable radio: Portable radios can use different types of power sources. Some portable radios require batteries, while others can be powered by electricity or have a combination of both options. Therefore, it depends on the specific portable radio model.
4. Cell phone: Cell phones today are commonly powered by rechargeable batteries. They can be charged using a power outlet or through wireless charging. Therefore, cell phones do use batteries.
In summary, the devices that do not use batteries are the microwave and the portable radio (depending on the specific model).
