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 )
_____________________________________________________________________
Answers
aa)
Equation for the R.M.S is,
Since,
And
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.
