See #28 and #29. The book answer for #28 is a) .283 A and b) 2.26 A and the book answer for #29 is a) .095 A and b) .012 A. I understand from the formulas why these are the answers. Could you explain in words what is it about the nature of a capacitor that causes the current through it to increase as the frequency of the alternating emf increases? Likewise, what is it about the nature of a...
