A.C Fundamentals (Solved Examples)

Problem 1

aa)      Prove that the R.M.S of,
V = k + A Sin wt   is,

Where, v1 = A Sin wt   and k is a D.C Component (constant).

bb)      Find the R.M.S Voltage of
V = 10 + 5 Sin (300t + 600 )  



Equation for the R.M.S is,



Cos 2π – Cos 0  =  1 – 1  = 0

bb)      This is a sin wave with a D.C Component. So We can use the equation we derived above.
