when current lags behind voltage how does it affect the
circuit.In other words what is the significance of lagging
current?
Answer Posted / puneet kumar
whenever ciruit contains inductive reactance(absence of
capacitive reactance) then current is lagging in nature
always in between 0 to 90 deg. depending on the impedence.
significance of lagging current means circuit has
inductive reactance surely which cause poor power factor
and this cause increase in imaginary loss turn to wastage
of energy due to poor p.f.
