Question 16: With (v(t)=Asin(ωt+ϕ)), where A, ω, and ϕ are constants,…

Question 16

+2 marksOne correct option

With (v(t)=Asin(ωt+ϕ)), where A, ω, and ϕ are constants, and the reference waveform featuring ϕ=0 (rad), examine the sinusoidal waveforms as shown below. Choose the appropriate waveform(s) concerning the reference waveform.

1. A

   Sin A = A sin(ωt−30 ) and Sin C = A sin(ωt+90 )

2. B

   Sin A = A sin(ωt+30 ) and Sin C = A sin(ωt+90 )

3. C

   Sin A = A sin(ωt−30 ) and Sin C = A sin(ωt-90 )

4. D

   Sin A = A sin(ωt+30 ) and Sin C = A sin(ωt-90 )
