## Frequency in a circuit using complex notation

1. The problem statement, all variables and given/known data

The frequency, ω, of the source in the circuit of Figure 2 is adjusted until ig is in phase with vg.

(a)using complex notation, determine the value of ω (rad/sec)
(b)if vg = 20 sin ω t [where ω is the frequency found in 2(a)], determine an expression for the output voltage, v0

2. Relevant equations

3. The attempt at a solution
See attached attempt on Question A & B - can someone advise if it looks right?

 Recognitions: Homework Help I think your frequency ended up being one order of magnitude too high. Check your math.
 Thanks gneill. Ah so where I have 10 to the power of 8, it should be to the power of 6?

 Quote by hockeynut Thanks gneill. Ah so where I have 10 to the power of 8, it should be to the power of 6?
Well, you've got both 106 and 108 in the relevant area of your work, so you really should be more specific. But yes, that is the issue.
