Q1:

Two sinusoidal waves 1 and 2 have peak values Vm1 and Vm2. Wave 1 is leading wave 2 by ∠θ. Which of the following is correct?

A v1 = Vm1 sin θ and v2 = Vm2 cos θ

B v1 = Vm1 sin ωt and v2 = Vm2 sin (ωt - θ)

C v1 = Vm1 sin (ωt + θ/2) and v2 = Vm2 sin ωt none of the above

D none of the above

ANS:B - v1 = Vm1 sin ωt and v2 = Vm2 sin (ωt - θ)

A leading B means B lagging A by ∠Q.
