In this short piece of the article, we are going to derive an expression for the RMS value of an alternating voltage, so let’s get started… Root mean square value of an alternating emf It is defined as that value…

## Expression for the RMS value of alternating current for a full cycle

In this short piece of article, we will derive an expression for the root mean square value of alternating current for a full cycle, so let’s get started… Root mean square (RMS) or virtual or effective value of AC It…

## Derive an expression for the average or mean value of AC for half cycle

In this short piece of article, we will derive an expression for the average or mean value of AC for half cycle, so let’s get started… What is the average value of AC? It is defined as that value of…

## Alternating current class 12 – amplitude, time period, frequency

In this article, we will discuss alternating current class 12, its amplitude, time period, and frequency, so let’s get started… What is an alternating current? Alternating current (AC) definition: An alternating current (AC) is an electric current that periodically reverses…
