A) IL > IC

B) IL = IC

C) IL> < IC

 I= I_L + I_R + I_C = V/Z_L + V/Z_R + V/Z_C = V(1/Z_L+1/Z_R+1/Z_C)=V(Y_L+Y_R+Y_C)=V*Y

Where Y represents the reciprocal of impedance and is called admittance.

Impedance angle θ = Tan ^-1 ((I_L - I_C)/I_R) = Tan ^-1 ((1/X_L – 1/X_C )/1/R)= Tan ^-1 (R (1 / ωL - ωC))
