The reactance of capacitor at 50 ~Hz is 5 . If the frequency is increased to 100 ~Hz , the new reactance is
Options
- A5
- B2.5
- C10
- D125
Correct answer
C. 10
Step-by-step solution
aligned X _ C & = 1 2 fc C & = 1 2 f (5) . ( X _ C =5 ) aligned New reactance, X _ C ^ = 1 2 f ^ C = 1 2 (2 f ) C = X _ C 2 = 1 2 5=2.5
