Graphing power p(t) with voltage v(t) and current i(t) given?

  1. Sep 4, 2008 #1
    I'm having a little trouble relating the graphs of voltage, current, and power together. I am given graphs of v(t) and i(t) and I need to sketch p(t). I know p(t) is (v*i), so do I need to integrate the slopes of the values for v(t) and i(t) under a definite integral (to get the discrete values) or to find the area of the curves of the graph, then multiply them together under (v*i)?

    Just multiply v and i. No integration, no derivatives, no calculus whatsoever.
