KVPY2017PhysicsAlternating Current
Consider the R-L-C circuit given below. The circuit is driven by a 50 ~Hz AC source with peak voltage 220 ~V . If R =400 , C =200 F and L =6 H , the maximum current in the circuit is closest to
Options
- A0.120 ~A
- B0.55 ~A
- C1.2 ~A
- D5.5 ~A
Correct answer
A. 0.120 ~A
Step-by-step solution
X _ L = L =2 50 6=600 X _ C = 1 C = 1 2 80 200 10⁻⁶ = 100 2 = 50 I _ = V z = 220 R ²+ ( X _ L - X _ C )² = 220 400²+ (600 - 50 )² I _ =0.120 ~A
