The same circuit when connected to a DC source of 12 V, gives a current of 0.4 A. What is the charge on the capacitor? Homework Equations Q(t) = Q 0 cos(wt), w = angular frequency = 1 / sqrt(LC), L = inductance Equations E = CV 2 2 E = C V 2 2 = RC = R C Where: The site owner may have set restrictions that prevent you from accessing the site.
