  1. A4 ~A and ⁻¹ ( 4 5 )
  2. B5.3 ~A and ⁻¹ ( 3 4 )
  3. C4 ~A and ⁻¹ ( 4 3 )
  4. D5.3 A and ⁻¹ ( 4 3 )

Correct answer

C. 4 ~A and ⁻¹ ( 4 3 )

Step-by-step solution

Circuit given is, Inductive reactance of circuit, aligned & X_L=L =L .2 f & X_L= 1 6 2 60 X_L=20 . aligned impedance of circuit, aligned Z & = X_L^2+R^2 = (20)^2+(15)^2 & = 625 =25 aligned Current in circuit, I= V Z = 100 25 =4 ~A Phase difference between voltage and current is given by = X_L R = 20 15 = ⁻¹ ( 4 3 )
