A coil having an inductance of 1 H is connected in series with a resistance of 300 . If 20 ~V from a 200 ~Hz source are impressed across the combination, the value of the phase angle between the voltage and the current is
Options
- A⁻¹ ( 5 4 )
- B⁻¹ ( 4 5 )
- C⁻¹ ( 3 4 )
- D⁻¹ ( 4 3 )
Correct answer
D. ⁻¹ ( 4 3 )
Step-by-step solution
aligned & X _ L = L = L 2 f & X _ L = 1 2 200 & X _ L =400 aligned Now, the phase angle' between voltage and current is given by, X_L R = 400 300 = ⁻¹ ( 4 3 )
