WebThe size of the phase angle will be determined by the ratio between resistance and capacitance. The series RC circuit vector is similar to the RL circuit in that it uses the common current element as the reference vector. WebA closer look at the phase angle mapping, and it looks like the admittance phase angle is just the reflection of the impedance phase angle about the real/X axis. For example, an impedance phase angle of 45 degrees is equal to an admittance phase angle of -45 degrees. And this makes sense if I had used some identities above:
