I am looking at a simple ac source in series with a capacitor. In the book I have it says that "initially when the capacitors plates are uncharged,they will not oppose or react against the changing current and therefore maximum current will flow and reactance will be low. As the capacitor charges it will oppose or react against the charge current , which will decresase, so the reactance will increase." i look at the capacitor voltage and current waveform and that seems right.Then the book says The discharge current is also hiest at the start of discharge as the voltage of the charged capacitor is also high. the confusion start there. When I look at the waveforms just agter the positive peak of cap voltage the current is minimum not max.Can you straighten me out. Also have had no calculus but can see when cap first starts charging although current is maximum the rate of change of current is minimum and when cap voltage is max current is minimum but its rate of change is maximum. Can you eplain that to me? Thankyou
