Question

Which of the following is the correct relationship between PEAK value and R.M.S. value of an alternating signal?
Options
A peak = r.m.s. x √2
Correct Answer
B r.m.s. = peak x √2
C peak = r.m.s./√2
D peak = √2/r.m.s.
Correct Answer

Option A is the correct answer.

Detailed Explanation

For a sinusoidal alternating current or voltage, the RMS (Root Mean Square) value is related to the peak (maximum) value by the formula VRMS = Vpeak / √2. Rearranging this, Vpeak = VRMS × √2.

Hint

RMS value is effectively the 'average' value over time, while peak is the maximum instantaneous value. Think about the 'factor' that relates them.
