Capacitive control

Jump to navigationJump to search

An alternative to inductive control is to employ a capacitor in series with the choke and therefore to obtain a leading power factor for the circuit. The current in a capacitive circuit is less affected by changes in voltage than that in an inductive circuit. Therefore, should there be a sudden drop in mains voltage, the capacitively controlled lamp is less likely to be extinguished than the inductively controlled lamp. Roberts, 2
