The phosphors for which of the following pair are 180° out of phase for VL, VC and VR______?
Correct answer: C. Vc and VL
- A. Vc and VR
- B. VL and VR
- C. Vc and VL
- D. none of the above
Explanation
In a series AC circuit, the inductor voltage leads current by 90° and the capacitor voltage lags by 90°, making V_L and V_C 180° out of phase. V_R is in phase with current.
