Question

The inductive reactance of an inductor of fraction numerator 1 over denominator pi end fraction henry at 50 Hz frequency is

  1. fraction numerator 50 over denominator pi end fractionohm    
  2. fraction numerator pi over denominator 50 end fraction ohm    
  3. 100 ohm    
  4. 50 ohm    

The correct answer is: 100 ohm


    X subscript L end subscript equals 2 pi nu L equals 2 cross times pi cross times 50 cross times fraction numerator 1 over denominator pi end fraction equals 100 capital omega
