Rev 2.02 E5B07 The phase angle between the voltage across and the current through a series R-L-C circuit if XC is 500 ohms, R is 1 kiliohm, and XL is 250 ohms is 14.0 degrees with the voltage lagging the current. Tangent of θ = Y / X or Tangent of θ = 250 / 1000 or Tangent of θ = .25 or θ = -14.04° E5B08 The phase angle between the voltage across and the current through a series R-L-C circuit if XC is 100 ohms, R is 100 ohms, and XL is 75 ohms is 14 degrees with the voltage lagging the current. Tangent of θ = Y / X or Tangent of θ = (75-100)/100 or Tangent of θ = -.25 or θ = -14.04° Rules for calculating impedances and phase angles E5B09 The relationship between the current through and the voltage across a capacitor is that the current leads the voltage by 90 degrees. E5B10 The relationship between the current through an inductor and the voltage across an inductor is that the voltage leads current by 90 degrees. E5B11 The phase angle between the voltage across and the current through a series RLC circuit if XC is 25 ohms, R is 100 ohms, and XL is 50 ohms is 14 degrees with the voltage leading the current. Tangent of θ = Y / X or Tangent of θ = (50-25)/100 or Tangent of θ = -.25 or θ = 14.04° Jack Tiley <strong>AD7FO</strong> Page 42 3/15/2009
