ABSTRACT:
The orientation of a polarized capacitor is determined by applying a voltage signal to one of the leads of the capacitor and a reference signal to the other lead. The magnitude of the electric field thus generated by the capacitor is measured. Then the voltage signal and the reference signal are reversed. The magnitude of the new electric field thus generated by the capacitor is measured. The ratio of the magnitudes of the first measured electric field to the second measured electric field is computed. If the ratio is greater than one, then the capacitor is determined to be properly oriented. If the ratio is less than one, then the capacitor is determined to be improperly oriented.
