Wave A = 100 sin ωt and wave B = 100 cos ωt. Then
A:
rms values of the two waves are equal
B:
rms values of A is more than that of B
C:
rms values of A is less than that of B
D:
rms values of the two waves may or may not be equal
Answer: A

Since peak values are equal, their rms values are equal irrespective of phase difference.
