1. The problem statement, all variables and given/known data What is the shortest time after which there would be no measurable charge on a 5.0 microfarad capacitor that is charged, then discharged across a 2000 ohm resistance. a. 0.001 s b. 0.5 s c. 10 s d. 3600 s 2. Relevant equations 3. The attempt at a solution According to the time constant the charge on the capacitor should decrease by a factor of 1/e every 0.01 s according to my calculation. I don't know how to answer the question though.
