The voltage of an $ac$ source varies with time according to the equation $V = 100 \sin(100 \pi t) \cos(100 \pi t)$,where $t$ is in $seconds$ and $V$ is in $volts$. Then:

  • A
    The peak voltage of the source is $100 \, V$.
  • B
    The peak voltage of the source is $50 \, V$.
  • C
    The peak voltage of the source is $100 / \sqrt{2} \, V$.
  • D
    The frequency of the source is $50 \, Hz$.
