Concept

Problem: Draw the resistor's voltage and current phasors at t = 15 ms. The figure (Figure 1) shows voltage and current graphs for a resistor. Draw the vectors with their tails at the origin. The orientation of your vectors will be graded. The exact length of your vectors will not be graded.

Voltage:

V=V0cos(ωt)

Current:

I=I0cos(ωt)

Angular frequency:

ω=2πf

f = 1/T

From the figure, the period T = 0.04s

The period is the time taken to complete one oscillation.

f = 1/0.04 = 25 Hz

ω = (2π)(25) = 157.08 rad/s
