The instantaneous value of an alternating current is given by I =50 (100 t ) . It will achieve a value of 25 ~A after a time interval of ( 30^ =0.5 )

Options

  1. A1 300 ~S
  2. B1 100 ~S
  3. C1 200 ~S
  4. D1 600 ~S

Correct answer

D. 1 600 ~S

Step-by-step solution

aligned & i =50 100 t & 25=50 100 t & 25 50 = 100 t & 1 2 = 100 t & 100 t = 6 & t = 1 600 ~S aligned
