Q1:

In figure

A Wave A is lagging wave B by ∠θ

B Wave A is leading wave B by ∠θ

C Wave A is lagging wave B by ∠θ and the two waves have same rms values

D Wave A is lagging wave B by ∠θ and the two waves have different rms values

ANS:B - Wave A is leading wave B by ∠θ

Wave A starts its cycle θ° earlier than wave B.
