The current in the inductive circuit is 10 A and power factor is 0.866. The phasor
representation of current is:

Correct option is A

Given-
Im=10 A
Power factor =0.866 lagging (∵ inductive circuit)
∴cosϕ=cos-1(0.866)
∴ϕ=-30∘ (∵ lagging power factor) So that phasor representation of current is given by
I=10∠-30∘ A
