WebWe use the integral form of the capacitor equation to solve for v (t) v(t) in three separate chunks: before, during, and after the current pulse. Before the pulse Before the current pulse (t < 0) (t < 0), no current is flowing, so no charge accumulates on \text C C. Therefore, v_ { (t<0)} = 0 v(t<0) = 0. We didn't even have to use the equation. WebApr 10, 2024 · I'm trying to find a If and AND formula to use for entering values under the date columns to return me those values..
