| May 10 at 3:14 | comment | added | Ale..chenski | Also, get a known good 100k resistor and measure the fall time just as you did with the scope alone. I suspect your capacitor is just effectively a 10nF cap. | |

| May 10 at 2:10 | comment | added | Ale..chenski | What kind of capacitor do you have? How do you know it is 100nF? | |

| May 10 at 1:44 | comment | added | Ale..chenski | What do you mean "I apply 5V", apply using what source? Are you watching how the cap charges, or how it discharges after your 5V source gets disconnected? | |
