When is tanφ negative?(a) When inductive reactance is less than capacitive reactance(b) When inductive reactance is greater than capacitive reactance(c) When inductive reactance is equal to capacitive reactance(d) When inductive reactance is zero

Answer» The correct option is (a) When inductive reactance is less than capacitive reactance

To explain I would say: tanφ is negative when inductive reactance is less than capacitive reactance because current will lead the voltage.
