The voltage supplied to a circuit is given by `V=V_(0)t^(3/2)`, where t is time in second. Find the rms value of voltage for the period, t=0 to t=1s.

Answer» The mean square voltage,
`barV^(2)=1/tint_(0)^(t)V^(2)dt=1/tint_(0)^(t)t^(3)dt`
`=V_(0)^(2)/4[t^(4)/4]_(0)^(1)=V_(0)^(2)/4`
`therefore = sqrt(barV^(2)) = V_(0)/2`
