Find rms value of voltage given in Fig.

Text Solution

Verified by Experts

In Fig. we find, `V = V_(0)` form 0 to `T//4` and `V = 0` for the next three quarters of time period.
`:. V_(rms) = sqrt((V_(0)^(2) + 0 + 0 0)/(4)) = (V_(0))/(2)`
In Fig. we find `V = V_(0)` form 0 to `T//2` and `V = 0` from `T//2` to T.
`:. V_(rms) = sqrt((V_(0)^(2) + 0)/(2)) = (V_(0))/(sqrt2)`
