The maximum value of an A.C. voltage coming in our houses is ………. % more than that of its r.m.s. value.

A

1.414

B

4.14

C

14.14

D

41.4

Text Solution

Verified by Experts

The correct Answer is:
D
`(DeltaV)/V_"rms" =(V_m -V_"rms")/V_"rms"=(sqrt2V_"rms"-V_"rms")/V_"rms"`
`=sqrt2-1=1.414-1.00`
=0.414
`therefore` Percentage increases
`(DeltaV)/V_"rms" xx 100 =0.414xx100%`
=41.4%
