An inductive circuit contains a resistance of 10 and an inductance of 2 H . If an AC voltage of 120 ~V and frequency 60 ~Hz is applied to this circuit, the current would be nearly

Options

  1. A0.72 ~A
  2. B0.16 ~A
  3. C0.48 ~A
  4. D0.80 ~A

Correct answer

B. 0.16 ~A

Step-by-step solution

Here, R=10 , L=2 H , V=120 ~V , v =60 ~Hz X_L= L=2 v L=2 22 7 60 2=754.3 = R^2+X_L^2 = 10^2+(754.3)^2 =754.35 _V= V Z = 120 754.3 ~A =0.16 ~A
