In the circuit of figure, V = - 300 sin (100 t - 20°) and I = 20 sin(100t - 146.9°). Determine R and X.

Attention:    In the Ufrgs list there are some typing errors. In current I, rather than ωt, is 100t. In the drawing the current I is not represented. See circuit above with correction. The answer appears X = C = 1250 uF.   X is the reactance in ohms. C is the capacitance in microfarads. Therefore, the correct answer is: R = 4 Ω,   X = 8 Ω   and    C = 1250 µF.
