Question

I'm charging a 5mF capacitor with a 5V battery through a $5\Omega$ resistor. When can I expect it to be fully charged?

• A. After 5 sec
• B. After 5 days
• C. After 5 years
• D. Never

Answer 1

The correct option is D Never

Look at the graph for charging shown in the videos. Clearly, the charge on the capacitor never hits the max value, or seems to hit it at infinity. In other words, the capacitor will never reach full 100% charge
