    hi,

    I'm learning simple high pass RC circuit currently. After calculation i get my result for my circuit is

    My question is, from my scope i can get phase shift of about 1.44rad for the theta value where Vin lag Vout. It is very big different compare with my calculation above which is a 7.234rad. And then i figure out that 7.234rad = 414.42deg which is more than a 360deg full cycle. I cant figure why this happen.

    Can someone help me on this?

    thank you.

    Hello,

    7.234 = tanθ, not θ. Taking arctan(7.234) gives you 1.43 radians.
