TM 9-254 7-3. Alternating Current - Continued c. AC Power.  The power expended in an AC circuit is calculated by the formulas: NOTE The  phase  angle  q  is  the  difference  in  degrees  that  the  current  leads  or  lags  the  voltage  in  a reactive circuit.  The phase angle is determined by the formula: q = arctan X R Where: X is the inductive or capacitive reactance in ohms. R is the resistance in ohms. P = I2Z cos q P = IE cos q P = E2 cos q Z Where: P is the power in watts. E is the voltage in volts. I is the current in amperes. Z is the impedance in ohms. q is the phase angle in degrees. Table 7-2 shows the basic voltage, current, and power relationships for AC circuits.
