1. The problem statement, all variables and given/known data A 35 mH inductor with 1.0 resistance is connected in series to a 20 µF capacitor and a 60 Hz, 40-V (rms) source. Calculate the phase angle. 2. Relevant equations tan φ = (XL - XC) / R 3. The attempt at a solution Solving for φ: φ = tan -1 [(XL - XC) / R] XL = 2πfL = 13.194 Ω XC = 1/(2πfC) = 132.63 Ω R=1Ω Plugging those values in I get Φ = -89.5° = 270.48° I submitted the 270.48 but it's wrong?
