Question

Define A.C , its peak value and its rms value . Derive relation between them after evaluating the expression for rms value.

Answer 1

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.

Answer 2

the EMF and AC are expressed in terms of rms values. rms value means Root means square.
