How does a capacitor reduce line current?

By canceling the reactive power to motors and other loads with low power factor, capacitors decrease the line current. Reduced current frees up capacity; the same circuit can serve more load. Reduced current also significantly lowers the I 2 R line losses. Capacitors provide a voltage boost, which cancels part of the drop caused by system loads.
