NEET2016PhysicsAlternating CurrentActual
A 100   Ω resistance and a capacitor of 100   Ω reactance are connected in series across a 220 V source. When the capacitor is 50 % charged, the peak value of the displacement current is
Options
- A2.2 A
- B11     A
- C4.4     A
- D11 2 A
Correct answer
A. 2.2 A
Step-by-step solution
Given, R = 100   Ω , X C = 100  Ω . Z = X C 2 + R 2 = 100 2   Ω . V max = 220 2   V . I max = V max Z = 220 2 100 2 = 2.2   A .
