NEET2010PhysicsAlternating CurrentActual
In the given circuit the reading of voltmeter V₁ and V₂ are 300 ~V each. The reading to the voltmeter V ₃ and ammeter A are respectively
Options
- A150 ~V , 2.2 ~A
- B220 ~V , 2.2 ~A
- C220 ~V , 2.0 ~A
- D100 ~V , 2.0 ~A
Correct answer
B. 220 ~V , 2.2 ~A
Step-by-step solution
For series L C R circuit voltage V = V _ R ^2+ ( V _ L - V _ C )^2 Since, V_L=V_C hence V=V_R=220 ~V also, current i = V R = 220 100 =2.2 ~A
