CST 212 Exam 1
1. A) Determine the angular velocity of a sine wave having a
frequency of 100 Hz.
The angular velocity is
= 2f =2*100 = 200
B) What is the phase relationship between the sinusoidal
waveforms of each of the following sets? Sketch the i and v
waveforms
• V = 10 sin(ωt + 10), I = 5 sin(ωt + 40)
The phase of V is laggard behind that of I by 30.
``
• V = 30 sin(ωt – 70), I = 20 sin(ωt + 20)
The phase of V is laggard behind that of I by 90.
