1. For the circuit shown in (Figure 1) , where V= 2.8 cos(2 t+ 0.3 ) , R= 8 Ω and C= 4×10−2 F , find the average power supplied by the source, Ps and the average power absorbed by the resistor PR . 2. p (t) = v(t)i(t) = VmIm cos (ωt + θv) cos (ωt + θi) PR = (1/2)(V2m/R) 3. From the expression given, I've managed to isolate the value of omega and Vm. But I'm confused as to how to find the power if we're not given an expression for the current.
