  • Question

  • Two resistors R1 = 36 ? ± 5% and R2 = 75 ? ± 5% are connected in series. The total resistance is


  • Options
  • A. 111 ± 0 ?
  • B. 111 ± 2.778 ?
  • C. 111 ± 5.55 ?
  • D. 111 ± 7.23 ?

  • Correct Answer
  • 111 ± 5.55 ? 

    Explanation
    Two resistors R1 = 36 ? ± 5% and R2 = 75 ? ± 5% are connected in series. The total resistance is 111

    Total maximum error ± (1.8 + 3.75) = ± 5.55 ?.
