Estimate Time to Charge a Battery
For this project, think about an electronic device with a battery that you have to charge on a regular basis.
- What device is it?
- When you are using the device, approximately how long does it take the battery to go from 100% charged until the time you need to plug it in again to recharge?
- Approximately how long does it take to charge to 100% starting from 0% or nearly 0%?
- Approximately how long does it take to charge if you plugged in your device when the battery was 50% charged?
- How long do you think it would take to recharge the device to 100% from 50% compared to the time it would take if the device was at 0%? Would it be exactly half the time, more than half the time, or less than half the time it would take if starting from 0%?
