    Reason (R): As per initial vaue theroem
    Assertion (A): If , the initial value of i(t) is 5A Reason (R): As per initial vaue theroem Both A a


  • Options
  • A. Both A and R are correct and R is correct explanation of A
  • B. Both A and R are correct but R is not correct explanation of A
  • C. A is true, R is false
  • D. A is false, R is true

  • Correct Answer
  • Both A and R are correct and R is correct explanation of A
     

    Explanation
    Initial value theorem when applied to I(s) gives 5 A.
