Time Constant: Why?

  1. Oct 2, 2007 #1
    I was doing a lab about filters and the professor asked us, as an extra for the lab report, to explain why [tex]\tau = RC[/tex] and why [tex]\tau = 63 \% [/tex] of the total rise or decay.

    To be completely honest, I really don't know the answers for either question. I know it makes sense for [tex]\tau = RC[/tex] if you just plug it into the formula.

    Anyone have any ideas on how to explain this?
