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

Click For Summary
SUMMARY

The discussion centers on graphing power p(t) derived from voltage v(t) and current i(t). Participants clarify that power is calculated as the product of voltage and current (p(t) = v(t) * i(t)). There is no need for integration or calculus; the power can be directly obtained by multiplying the corresponding values of voltage and current at each point in time. This straightforward approach simplifies the process of sketching the power graph based on the given voltage and current graphs.

PREREQUISITES
  • Understanding of basic electrical concepts, specifically voltage and current.
  • Familiarity with the relationship between power, voltage, and current.
  • Ability to interpret graphs of functions over time.

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.
