Your phone is at 1%. You plug it in at 9 p.m., and at 7 a.m. it's still at 1%. The charger and the outlet both work. What happened?
Hint: What did you do right before bed?
Answer
The outlet is controlled by a light switch, and you turned it off
Some outlets are wired to a wall switch, so switching off the light cuts the power.
Did you get it?
Nice work. On to the next one.
Got you this time. Try the next one.
