These are the questions which come in our minds every time when we are dealing with AC circuits.Suppose, we have a simple DC circuit (figure – 1) and we want to replicate it in an AC circuit. We got every thing same, except supply voltage which is now to be an AC supply voltage. Now, the question is what should be the value of AC supply voltage so that our circuit works exactly same as that of DC.Let us put same value of AC supply voltage (AC Vpeak = 10 volt) which is in our DC circuit. By doing
