The r.m.s. value of potential difference V shown in Fig. is

Answer»

`V_(0)`
`V_(0)//2`
`V_(0) //sqrt2`
`V_(0) //sqrt3`

Solution :From graph we note that in TIME interval 0 to `T//2` the POTENTIAL diff. `= V_(0)` (constant) and in time interval `(T)/(2)` to `T`, the potential DIFFERENCE = 0.
`:. V_(RMS) = sqrt((V_(0)^(2) xx (T)/(2) xx 0^(2) xx T//2)/(T)) = (V_(0))/(sqrt2)`
