Why do lamp manufacturers install capacitors in fluorescent lighting fixtures?
What will be an ideal response?
The reactor or voltage ballast in series with the fluorescent tube causes the power factor of fluorescent units to range from a 50- to 60-percent lag. Power companies, therefore, have requested that fluorescent lamp manufacturers install capacitors in fluorescent lighting fixtures to achieve power factor correction. Most fluorescent lighting units have such a capacitor connected in the lamp circuit so that the operating power factor of most fluorescent lamp units is near 100 percent or unity.
