Question

powering a cell phone
cell phones are dependent on your home power supply.
true
false

Explanation:

Cell phones are powered by their internal batteries, which are charged using a power source (like a home power supply via a charger), but the statement implies a direct dependency on home power supply for operation at all times. However, once charged, cell phones can operate independently of the home power supply. But the question is about dependency for powering (charging the battery which is needed for operation). Wait, actually, to power the cell phone (charge its battery), it does depend on a power supply (often home power supply for charging, though there are other ways like solar chargers, but the common way is home power). Wait, no—if the statement is "Cell phones are dependent on your home power supply" for powering (i.e., getting energy to operate), then technically, to charge the battery (which powers the phone), they often use home power, but the phone itself (when using the battery) isn't dependent on home power. But the question is about "powering a cell phone"—the process of providing power. Since cell phones need to be charged (usually via home power, though other options exist, but the common case is home power for charging). Wait, no, the correct answer: Cell phones can be charged via home power, but they also can be charged via other sources (like car chargers, solar). However, the statement says "dependent on your home power supply"—if "dependent" means they must use home power, that's false. But if it's about the primary way to charge (power the battery), maybe? Wait, no—cell phones are powered by their batteries, and the batteries are charged by a power source, which can be home power, but they aren't dependent on home power (they can be charged elsewhere). So the statement is False.

Answer:

False
