Q1:

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

ANS:A - rms values of the two waves are equal

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