Hello everyone, I'm brand new here and hope I've chosen an appropriate section to post this in.
I'm learning about circuits and curiosity about transistors made me wonder if I would get a delayed response by hooking 5V to the transistors trigger pin through a 100uF capacitor. What I got instead puzzles me and I'm hoping somebody here can explain what's happening in my circuit. I have included a link to a video where you can see the behavior in action.
Video:
Essentially, there was no response when hooking up 5V through the capacitor but I got a response by touching the top of the capacitor with my finger despite it being hooked up to nothing. I assume the capacitor was storing charge and I was just assisting in making a connection through the breadboard so I pulled the capacitor out and re-seated it and I'm sure there is a good connection but I got the same result.
Thanks in advance for helping out a novice. I'm sure the answer will be embarrassingly simple but I haven't been able to figure it out on my own and google isn't much help on this one.
EDIT: I should have been clearer in the video: The LED anode is connected to the emitter and the cathode to ground through a 330ohm resistor. The transistor is an S8050
