Sorry to say, but the capacitance does change depending upon the applied voltage. As you increase the plate voltage a force is created pulling the plates together. This effectively INCREASES the capacitance. The good news is that this enhancement is (...) (25 years ago, 22-Apr-99, to lugnet.robotics.handyboard)

As long as we are talking about caps, I cannot find the information about why one uses tanatlum caps vs ceramic caps vs electrolytic. What are the differences between the various types? Thanks, Gary Livick (25 years ago, 22-Apr-99, to lugnet.robotics.handyboard)

Generally, cost, accuracy, size, and drift. Ceramic caps are expensive ($/pf) reasonably stable across temperature and acceptably accurate. Electrolytic capacitors are cheap ($/pf) only moderately stable across temperature changes, polarized, and (...) (25 years ago, 22-Apr-99, to lugnet.robotics.handyboard)
