Question

I found the answer but I'm not sure I'm doing it correctly, so can some one explain how to do these problems.


Problem 1

The phase relationship between the following pair of waveforms:

b) v = 10 V sin(ωt ─ 40°) i = 2 A sin(ωt ─ 25°)

c) v = 120 V sin(ωt + 60°) i = 16 A sin(ωt + 15°)


Problem 3

The rms values of the following sinusoidal waveforms:

b) i = 2.3 x 10^-3 A sin(2πt ─ 10°)

c) v = 5 x 10^-6 V sin(377t + 80°)

Top Answer

1)here we are two sinusoidal signals a) v = 10 V sin(t 40) i = 2 A sin(t 25) writing them into phasor form... View the full answer
