What is dissipation factor in schering bridge

Therefore values of capacitance C and its dissipation factor are obtained from the values of bridge elements at balance. In physics, the dissipation factor (DF) is a measure of loss-rate of energy of a mode of oscillation (mechanical, electrical, or electromechanical) in a dissipative. After the bridge is balance the manual.
