An $AC$ current is given by the expression,$I(t) = 50 \sin(200 \pi t)$ in amperes. The frequency and $RMS$ value of the current respectively are

  • A
    $100 \text{ Hz}, 50 \sqrt{2} \text{ A}$
  • B
    $100 \text{ Hz}, 25 \sqrt{2} \text{ A}$
  • C
    $200 \text{ Hz}, 50 \sqrt{2} \text{ A}$
  • D
    $200 \text{ Hz}, 25 \sqrt{2} \text{ A}$
