A.C Fundamentals (Solved Examples 2)


1) Find the R.M.S of,
V (t) =   Sin 2πt +  Sin 6πt

Answer

First of all, We have to find the Period of this function.
We know that,
T = 2π/w
Here we have two sinusoidal functions (V1 & v2).

Figure 22.1 Show the Two sine functions individually. 

  ----- Sin 2πt
  -----Sin 6πt

Figure 22.1 Sin 2πt & Sin k2πt Functions individually, 

So now it is clear that sin2πt is the Primary wave.
T = 2π/w
Here w = 2π ,
Therefore,

T = 1

Now,
