Example:
Conversion
With
Vectors.
Engineer P.C. Bord has deter
mined that in the RC circuitshown on the next page at left, the total
impedance is 77.8 ohms and voltage lags current by 36.5°. What are
the values of resistance, R,
and
capacitive reactance,
Xc,
in the circuit?
Use a vector diagram as shown with impedance equal to the polar
magnitude, r, and voltage lag equal to the angle, 0, in degrees. When
the values are converted to rectangular coordinates, the x-value yields
R, in ohms, while the y-value yields
Xc,
in ohms.
