Question

Define alternating current it's peak value and rms value. derive a relationship betwn them.

Answer 1

Alternating current is an electric current which periodically reverses direction, in contrast to direct current which flows only in one direction. ... The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage

What is the relation between the RMS value and the peak value of AC?

Root mean square value or RMS is root 2 times of the peak value. Let us consider voltage with the peak value of V. So to get the RMS value of the voltage , we follow the equation as -

Vrms = V / square root of 2 = V / (2)^1/2 = V / 1.414

So from the above , Vrms = 0.707 * V.

Same equation goes with current too.

Answer 2

AC ( Alternative Current) occurs when charge carriers in a conductor or semiconductor periodically reverse their direction of movement. It is commonly used as household utilities and business.

RMS ( Root Means Square) value : The potential difference and current are varying continuously an average value for potential difference and current.

peak value : It is defined as the highest or lowest value of a certain electrical wave.
