So I got to the part of my math/engineering textbook on vectors and scalars, and I've got to calculate phase angles and voltage. I see this equation, and I've tried doing it different ways but I don't get correct answers.
tanθ=XL−XC / XR
Angle θ represents the phase angle between the current and the voltage.
I thought I was supposed to square each value first,
then subtract C from L,
then divide by R
then get the square root of the result,
then push the inverse button + Tangent on the calculator to change the result into an angle in degrees.
I didn't do well with vector spaces in school and have trouble with them now.
Also, am I supposed to do any RMS stuff like root 2 over 2, since its AC, and implied? Or am I overthinking it?
