From the given waveform (of current), sketch the energy from t = 0 to t = 2T. Given: R = 10 Ohms, i = 10 Amps
I'm having trouble with this even though it's probably really easy.
I know WR = ∫Ri2(t) dt
so for one period, for example, I have
∫10(102) dt with limits of integration from 0 to T/2
= 1000 t / t goes from 0 to T/2
= 500T
i believe this is a line with slope 500 going from 0 to T/2..but I'm not sure what i do for the other values of t
when i graph it should I just graph 1000t and plug in values for t?
