Hey guys i'm not really sure how to draw the graph
A current i(t) = 10cos(200πt) flows through a 100Ω resistance. Sketch i(t) andthe power p(t) to scale versus time. Find the average power delivered to theresistance.
For the power i just i drew two humps that are max at 10KW, they start from -2.5ms and then rise to the max at 0s at 10kW and then back down to 0 at 2.5ms then rises back up to max at 5ms and goes back to 0 at 7.5ms. So i didn't draw it like a proper cosine graph because it is squared and not sure if this is correct. With the current i drew it with the first half similar as it rises to max current at 10A and then goes down to -10A at 5ms where the power would be at max again in opposite phase, so the graph and two waves look out of phase and quite dodgy.
