    Very cool. Does it matter what kind of resistor you use?
  •  
  • Ben 2 years ago
    Patrick, the larger the resistor, the slower the charge will "drain" from the capacitor. Experiment with different resistors for fun!

  • Mike Dedmon 2 years ago
    Cool info, but... Why? What is the purpose of a capacitor? If you're getting power from a source, why do you need the capacitor? What does it do for you? I'm not clear on this at all
  • Art Dept UNCG 2 years ago
    It is to supply a measured and controlled charge.

  • Jan van Eyck 2 years ago
    fun and informative, though a suggestion for the creators: the music is unnecessarily loud in spots and competes for attention

  • Lorraine Loiselle 2 years ago
    Thank you once again. I'm new to electronics, and I look forward to your demystifying instructional videos, i.e. Why can't all teachers be like you?
