I posted this in the exam power thread. I got this problem wrong. I took it under "simulated" timed conditions, and the last thing I looked at were the graphs. It slipped my mind that the timer only runs for 5 hours, so the motor only runs at 10am, not 10am and 2pm. UGH!Tbh, reading this/solving this helped me calm down a bit. I forgot how much I liked simple circuit stuff. I wish I had explored it a bit more.
And I couldn't figure out why last night. I started posting it, and only then did I see my error.
